Description

Intelligent analysis method, system, equipment and medium for value of art work

Technical Field

The invention belongs to the technical field of computer information processing, and particularly relates to an intelligent method, a system, equipment and a medium for analyzing the value of an art work.

Background

With the continuous improvement of the quality of life of people, the potential psychological demands on the quality of life and the mental civilization construction drive make people attach more and more importance to the personalized work display and the affirmation of the self value. The artificial intelligence is accompanied with the continuous progress of machine learning and deep learning algorithms, and under the environment that the multimedia network is widely applied, the intelligent algorithms are applied to various fields in life, so that a new man-machine interaction form and a professional skill tool are provided for users.

The first prior art is as follows: CN201710865048.2 artistic work selecting method and system. The method and the system for evaluating and selecting the works of art provided by the invention can evaluate and select the works of art for competition for an exhibition on line, increase the popularization range, are convenient and simple, and simultaneously reduce the contribution cost of an author and the evaluation cost of a host; furthermore, the public and transparent evaluation is performed through the evaluation unit, so that the notarization degree and the notarization ability in the evaluation process are increased, and the experience degree of the participants is increased; furthermore, the selecting unit selects the selecting information of the artwork through the receiving client, the selecting mode is fair and fair, the enthusiasm of the author in competition is stimulated, and the system has practicability. Although the selection mode is public and fair, the evaluation of the quality of the work still adopts a manual evaluation mode, so that the subjectivity is strong, and the real fairness and fairness cannot be realized.

The second prior art is: CN201710919334.2 art appreciation ability evaluation method, evaluation server and evaluation system. The invention provides an art appreciation ability evaluation method, wherein the evaluation method comprises a plurality of evaluation periods, and each evaluation period comprises the following steps: providing an electronic carrier of an artwork to be practiced to a appreciator, wherein the electronic carrier of the artwork to be practiced comprises pictures and/or videos of the artwork to be practiced; receiving an appreciation result made by an appreciator according to the electronic carrier of the artwork to be practiced; and scoring the appreciation ability of the appreciator by using a reference factor to obtain the appreciation ability score of the appreciator, wherein the reference factor comprises the market price of the artwork to be practiced and/or the score of the appreciation result by an expert. The invention also provides an evaluation server and an evaluation system for the art appreciation capability. The method for evaluating the art appreciation ability can be used for evaluating the art appreciation ability of the appreciator, thereby being beneficial to the appreciator to improve the appreciation level. Although the evaluation system is provided, statistics of the works and evaluation results thereof can be provided, the evaluation essence of the quality of the works still adopts a manual evaluation mode, and real fairness and justice cannot be realized.

The prior art is three: the design and implementation of the artistic work display platform for students are that the paper analyzes from the actual requirements of the system, and according to the software development flow, an MVC framework under a B/S mode is adopted, eclipse is used as a development environment, jsp is adopted to complete the design of a foreground interface, struts2 is used to complete the logic service processing of the system, a Microsoft SQL Server database is adopted, a hibernate framework is used to realize the data access, a file storage and web Server are tomcat, and the virtual reality is carried out through a VR technology, so that a main functional framework of the artistic work display platform integrating the display and the social contact is finally realized. Mainly is the programming realization mode of a system software system, and has insufficient innovation.

At present, a system for displaying, socializing and evaluating information related to artwork does not form a complete system, and functions are not complete. For example: the simple picture work uploading system has the defects of single form, incapability of realizing personalized display and the like. Due to the fact that the content of the works of art is diverse, abstract and complex, a simple traditional manual evaluation system is mostly used for evaluating the works, evaluation results have large subjective uncertainty due to different personal knowledge and experience, evaluation standards of the works of art are not uniform, and subjective factors dominate. Long period, strong subjective color; the evaluation difficulty of the existing automatic machine for the works is very high due to the lack of objective and timely guidance opinions.

The current common adopted method is manual evaluation mode, subjective factors are very strong, standards are not uniform, and the method is not beneficial to objectively evaluating the value of works. For example: at present, a Chinese painting style work X is a pair, experts A like Chinese paintings and score 90 is given; expert B likes caricature work, scoring 80. And what are the basis for the 90 and 80 points? Perhaps by feel alone, theoretical support is difficult. In addition, the manual evaluation mode is time-consuming and labor-consuming, a work is seriously evaluated, specific conclusions and improvement suggestions are given from the beginning of observation, and the time consumption is averagely 5-20 minutes according to different abilities of evaluators.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) A service problem. It is not practical to evaluate the increasingly dramatic works of art entirely by hand. Except taking relevant paying courses, most individuals do not have special teachers, cannot be guided by the special teachers in time, and are inconvenient to communicate and learn at any time and any place; the time of the expert or teacher is limited, and once too many works are produced, the time and labor are consumed for guidance, and the efficiency is low.

(2) The questions are evaluated. The evaluation result lacks certain objectivity and fairness. The machine automatic evaluation can guarantee objectivity and fairness, but AI artificial intelligence just starts in the aspects of perception and cognition of a human simulator to beauty, and when an evaluation model is established by using an AI algorithm, a massive work training set is needed, the existing work set, particularly the domestic work set, is very limited, and the modeling difficulty is further increased. Making it very difficult to technically implement automated evaluation.

The difficulty in solving the above problems and defects is:

(1) It is unlikely that everyone is equipped with a specialized art teacher and gets learning guidance anytime and anywhere; the chances of multiple people getting together to communicate with each other are also very limited.

(2) The evaluation of the art is not simply a mistake but an evaluation of skill and feelings such as skill and feeling. Recently, AI artificial intelligence technology has made great progress in the fields of object recognition, face recognition, behavior recognition, etc., so that the gap between the ability of computers in recognizing objects, distinguishing people, recognizing affairs, etc. and the human level is gradually reduced, even exceeding the human intelligence level in some specific application scenarios. However, compared with semantic features of object recognition, the human aesthetic rules have not been quantifiable scientific explanation, and the difficulty in selecting aesthetic feature points of the work is high, so that the difficulty in realizing accurate AI evaluation is very high.

(3) The AI algorithm establishes the accuracy of the model, and one of the key factors is the scale and number of the training data sets. The existing works, particularly domestic works, are very limited, and effective calibration of the works by professionals is lacked, so that the evaluation modeling difficulty is very high.

The significance of solving the problems and the defects is as follows: the system provides a platform for art learning, result display and interaction for everyone, and particularly can obtain objective, fair and efficient result evaluation and learning guidance.

The works decoration means that a plurality of different picture frames are selected for decorating the works, a client can adjust and select the decoration most suitable for the works of art, and the decorated works can be placed indoors or outdoors, on the wall of a living room or on a display wall of a painting exhibition. The selection is various, and the real application environment can be designed according to the selection.

(3) The work evaluation submodule mainly comprises functions of expert online comment, system AI intelligent comment, growth suggestion and the like.

1) The user and the teacher end can evaluate and score the artistic works in a four-dimensional evaluation mode, the only difference between the user end and the teacher end is that the expert evaluates and reviews the works on line, only the teacher end can review and guide the works, the function is that the expert or the teacher can evaluate and give professional guidance to the works of the user on line, and the system can provide a one-to-one mode for the two parties to communicate.

2) The AI intelligent evaluation function can realize the automatic evaluation of the works based on the calculation aesthetics aiming at different artistic works and present the works in a visual form. Taking a picture work as an example, by using indexes such as color, vision, technique, spaciousness, modeling, innovation, master matching degree, work potential value and the like, a machine learning algorithm is utilized to design a corresponding evaluation method and a reference judgment standard, and finally an evaluation report is obtained. The specific method for evaluating the AI intelligent evaluation parameters comprises the following steps:

a. the Color and the Color parameter are the comprehensive evaluation of the tone, brightness, purity and Color richness of the picture, and the evaluation function is shown in formula (1). Wherein color is a color total evaluation value, H is a hue evaluation value, V is a brightness evaluation value, S is a purity evaluation value, and F is a color richness evaluation value; t is t ₁ ～t ₄ The weight values of H, V, S and F, respectively, can be adjusted:

Color＝H*t ₁ +V*t ₂ +S*t ₃ +F*t ₄ (1)

H. v, S can be calculated by opencv library functions, and F is the parameter of the most difficult to evaluate metric and cannot be directly calculated by the existing algorithm. The evaluation method for design F is as follows: let the eight basic hues be: r (1,0,0) red, G (0,1,0) green, B (0,0,1) blue, Y (1,1,0) yellow, M (1,0,1) magenta, C (0,1,1) cyan, K (0,0,0) black, W (1,1,1) white. Firstly, the Euclidean distance between each pixel of the detected image and each basic tone is calculated, and the basic tone with the minimum distance is the color of the pixel. Then, the pixel number ratio of each basic tone is counted, if the sum of the pixel ratio of the black and white two basic tones exceeds 90%, the picture is determined to be gray tone (black and white tone), otherwise, the picture is determined to be color tone. In the color tone, whether the pixel ratio of the remaining 6 basic tones exceeds 5% is judged, if so, the basic tone is judged to be a prominent color, and a corresponding F value is obtained according to the number of the prominent colors. The basic decision criteria are shown in table 1.

TABLE 1 basic evaluation criteria for F values

b. The Vision Vision 'Vision' parameter embodies the grain distribution condition of the picture, and the higher the evaluation value is, the richer and finer the grain of the picture is. The evaluation method is as follows: analyzing the texture distribution of the pictures from the visual texture, graying each picture, and performing LBP algorithm processing to obtain a corresponding texture image; then, the entropy of each texture image is calculated in a quantitative mode, and the larger the entropy value is, the richer the corresponding texture is. Experiments show that the approximate distribution range of the texture image entropy values of all pictures is between 0 and 7. There is also a rule for the distribution of texture image entropy values: when the picture is a pure color picture, for example, a pure white or pure black picture, no texture exists, and the entropy value corresponding to the texture map is 0. With the continuous improvement of the richness of the image texture, the entropy value of the corresponding texture map is continuously increased and continuously approaches to 7, and finally, normalization operation is performed to limit the numerical value between 0 and 1, wherein the numerical value is divided into seven grades on average, 0 is the lowest grade (namely the lowest visual effect), and 1 is the highest grade (the best visual effect).

c. Technical Skill, the "technical" parameter embodies the composition capabilities of a picture composition. The common picture composition patterns include a straight line type, a triangle type, a polygon type, a circle type, an S type and the like, and pictures with different types of attributes have different picture composition modes. The picture is divided into two types of landscape painting and non-landscape painting for independent detection, the landscape painting mainly comprises a straight line type composition and an S type composition, the non-landscape painting has richer composition modes, and the detection method mainly comprises line detection. First, edge detection is performed on the picture, and then composition is detected in a classified manner. In the case of a landscape, a line or curve in the picture is examined that spans the entire picture (3/4 width or height). If yes, the picture is a straight-line or S-shaped picture composition; otherwise, judging that the picture has no obvious shape. If the picture is a non-landscape picture, a straight line crossing the whole picture (3/4 width or height) in the picture is checked, and if the straight line exists, the picture is in a straight line shape. Otherwise, detecting four edge points of the top, the bottom, the left and the right on the edge picture, and connecting the four edge points clockwise to form a quadrilateral shape, if the length l of a connecting line between two points is too short, if

When the two points are combined, the midpoint is taken to form a triangular shape. The relevant methods and reference criteria are shown in table 2.

TABLE 2 basic evaluation criteria for "composition" parameters

d. The Space sense Space and the Space sense parameter embody the feeling of the real object in a picture approaching to the reality. The common types include single-layer shielding, multi-layer shielding, virtual-real (convergence, divergence, shape, brightness, cold and warm, pure gray) contrast, size perspective and the like. And evaluating the 'spatial perception' parameters of the work picture from the three aspects of the existence of occlusion, the existence of contrast and the existence of perspective. The picture is tiled without shielding and without contrast, so that the space sense is weak; the picture has single-layer shielding and no other contrast, namely the space sense is weak; the picture has a moderate sense of space due to the fact that the picture has multiple layers of shelters; the picture has multilayer shielding, and the contrast of virtual and real is obviously strong spatial impression; the picture has multilayer shielding, obvious contrast between virtual and real images and obvious size perspective, which means that the space sense is stronger, and the evaluation standard is shown in table 3.

TABLE 3 basic evaluation criteria for spatial impression

Spatial perception grade	Evaluation criteria	Evaluation results (points)
			Is weaker	No space collocation and single-side tiling	<60
Weak point of weakness	Single layer shielding and comfortable space	60-70
			Is moderate	Multiple layers of shielding, basically conforming to the size of the near part and the distance part	70-80
Is stronger	Multi-layer shielding and obvious perspective	80-90
			Is very strong	Obvious level contrast, virtual-real contrast and large-small perspective	90-100

Due to the large evaluation difficulty and various types, an experienced expert can directly judge the 'spatial sensation' condition of one picture by naked eyes, so that the manual evaluation can realize the evaluation of the 'spatial sensation' parameter, but the degree of the 'spatial sensation' is different from person to person, and the manual evaluation cannot realize 'fairness'. In addition, human eyes can easily judge the 'spatial sense' parameter by experience and sense, but the machine is difficult to describe formally and cannot be realized by a traditional machine learning algorithm. Therefore, the evaluation of the 'spatial sense' parameter is realized by adopting an automatic evaluation method based on calculation aesthetics of deep learning.

First, a training data set is prepared. The training picture set is divided into 5 levels by experts according to the basic evaluation criterion of the spatial perception in the table 3 for deep learning network training. Then, preprocessing each picture, performing noise reduction processing on the pictures by adopting Gaussian filtering to remove noisy redundant information in the pictures, extracting a gray image from the filtered images, and converting pixel values of the obtained gray image into a pixel matrix with the size of 224 × 224. And performing convolution operation on the whole picture by adopting a convolution core of 3*3 to extract an image characteristic value, training by adopting a deep learning network resnet, wherein the number of the convoluted pictures batch _ size =16, the number of network cycle iterations epochs =200, 5 ganglion points corresponding to 5 grades are output by an output layer, each nerve node value is the probability of the classification to which the picture belongs, and the grade corresponding to the highest probability value is selected as a 'spacial sense' grade. And after the training is finished, the training model is stored, when the system inputs a test picture, the test picture is sent into the model to judge the affiliated grade, and finally the grade is converted into an evaluation result.

e. The Model' parameter reflects the shape and volume of the picture content, and is commonly a point Model, a line Model, a surface Model and a point-line-surface Model. And carrying out edge detection on the pictures, and then classifying and detecting the shapes. Firstly, whether the area of the middle point and the dot circle of the whole picture exceeds 2/3 is detected, if not, the picture is judged to have no obvious shape, and if so, the picture is in a dot shape or other shapes. And detecting the straight line of the whole picture in the picture, if the straight line is in a line type shape, then detecting whether all the lines are connected into a plane to form the line type shape, and if not, the straight line is in a point-line-surface type shape. The basic evaluation criteria of the "shape" are shown in table 4, and the "shape" parameters only have differences in category, and have no good or bad score, so the evaluation result is the detection result, and no score difference exists.

TABLE 4 basic evaluation criteria for the build

Class number	Detection standard	Evaluation results
			1	The area of the middle point and the circle of the whole picture is less than 2/3	Without moulding
2	The area of the middle point and the circle of the whole picture exceeds 2/3	Point type modeling
			3	Picture presenceStraight line	Line model
4	Stored online energy connected noodles	Surface type modeling
			5	2. 3 and 4 are both present	Dotted line surface modeling

f. Innovativeness and creativity embodied by the 'innovativeness' parameter are uniqueness of the picture in the aspects of texture, shape, color and the like. The method can be divided into dimensions of theme innovation, expression technique innovation, composition innovation, modeling innovation and the like. The parameter is similar to the 'spatial perception', the judgment of the picture 'innovation' parameter is easy to be made by the personal experience, but the machine is difficult to describe formally and cannot be realized by the traditional machine learning algorithm. Therefore, the evaluation of the 'innovative' parameters is also realized by adopting an automatic evaluation method based on calculation aesthetics of deep learning. The evaluation criteria are shown in table 5, with 5 levels according to the degree of "novelty". 20000 pictures of the works are manually evaluated and classified into the 5 grades respectively, and 5000 pictures are averaged for each grade. The training process is basically the same as the "sense of space" parameter, and the difference is two points: firstly, performing model training by adopting an Alex Net network; and secondly, training and learning the RGB three-channel colors by considering the colors of the images.

TABLE 5 basic evaluation criteria for innovations

Grade	Degree of innovation	Evaluation results (points)
			1	Is weaker	<60
2	Weak point of weakness	60-70
			3	Is moderate	70-80
4	Is stronger	80-90
			5	Is very strong	90-100

g. The master matching degree is evaluated by which the picture of the work is closest to which master or famous work, and the picture style of the author of the work is most similar to the picture style or the drawing method of which master or famous family, so that the evaluation is abstract, and the evaluation result cannot be obtained by using the traditional evaluation method. The invention adopts a 'deep learning' method, comprehensively obtains the similarity parameter values of the picture of the work and the work of which teacher from the aspects of composition, color, texture, space sense and the like, and the evaluation function is shown in a formula (2). Wherein, simila is a general evaluation value of 'master matching degree', SSIM is a structure similarity evaluation value, CSIM is a color similarity evaluation value, TSIM is a texture similarity evaluation value, and PSIM is a space sense similarity evaluation value; t 1-t 4 are the weighted values of CSIM, V, S and F respectively, and can be adjusted to default values of 0.25.

Simila＝SSIM*t ₁ +CSIM*t ₂ +TSIM*t ₃ +PSIM*t ₄ (2)

Taking the composition similarity evaluation value as an example, the specific steps are as follows: firstly, dividing master works into four categories, namely people, animals, landscapes and the like, and then selecting a corresponding master works set according to the type of an evaluated picture; then, the structural similarity CSIM between the evaluated picture and each picture in the master work set is calculated _i Maximum value as CSIM = CSIM _max The master work corresponding to the maximum value is the final matching work, and the master is the best matching master.

In conclusion, under the combined action of the parameter algorithms, the evaluation result is presented in a visual form.
