Fig. 1 is a flowchart of an image processing method according to an embodiment of the disclosure, and as shown in fig. 1, the flowchart may include:
step 101: an image of the motion field is acquired.
Here, the image of the motion field may be at least one frame image; when the number of at least one frame of image is more than 1, the image of at least one frame of motion field can be a continuous multiframe image or a discontinuous multiframe image; the image of the motion field may be acquired by an image acquisition device, which may be a mobile terminal or a device such as a camera independent from the terminal, for example, or may be acquired from a local storage area or through a data transmission means such as a network; for example, in the case of acquiring an image of a motion field by using a plurality of image acquisition devices, images acquired by the plurality of image acquisition devices at the same time may be fused to obtain an image of the motion field after fusion processing.
The format of the motion field image may be Joint Photographic Experts GROUP (JPEG), Bitmap (BMP), Portable Network Graphics (PNG), or other formats; it should be noted that, the format and the source of the motion field image are merely exemplified, and the disclosed embodiments do not limit the format and the source of the motion field image.
Step 102: and carrying out human body detection on the image of the motion field to obtain at least one human body image.
In practical application, a human body can be detected from the image to obtain a human body detection frame corresponding to the image, and the image selected by the human body detection frame is used as a human body image. In one implementation, the above implementation may be implemented by training the human body detection model in advance, or by using other implementations. Wherein the human body detection model is used for detecting a human body from the image. After the trained human body detection model is obtained, the image of the motion field can be input into the human body detection model, the image of the motion field is processed by the human body detection model, a human body detection frame corresponding to the image is obtained, and the image in the human body detection frame is the human body image.
The Network structure of the human body detection model is not limited in the embodiments of the present disclosure, and may be a two-stage detection Network structure, for example, the Network structure of the human body detection model is a fast-Regions with a probabilistic Neural Network (fast RCNN), etc.; the network structure of the human body detection model may also be a single-stage detection network structure, for example, the network structure of the human body detection model is RetinaNet.
It is understood that the image within the motion field may include one human body, or may include a plurality of human bodies; thus, a human body image or a plurality of human body images can be obtained by performing human body detection on the image of the motion field.
Step 103: aiming at each human body image in at least one human body image, identifying multiple attributes of the human body image to obtain identification results corresponding to the multiple attributes in the human body image; and determining the human identity information in the human image according to the obtained identification result.
Here, the various attributes include, but are not limited to, color, size, text, shape, etc. information. In practical application, each human body image can be identified by utilizing a pre-trained target attribute identification model to obtain an identification result of target attributes in the human body images; wherein the target attribute may be one of the above-mentioned plurality of attributes.
As an implementation manner, after the identification results corresponding to the multiple attributes in the human body image are obtained, the human body identity information in the human body image can be determined according to the predetermined corresponding relationship between the multiple attributes and the human body identity. In an actual scene, various corresponding attribute information can be prestored according to each human identity information, so that the corresponding relation between various attributes and the human identity is determined.
Step 104: and processing the images of the motion fields according to the human identity information of each human image in the images of each motion field.
In practical applications, the steps 101 to 104 may be implemented by a Processor in an electronic Device, where the Processor may be at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, and a microprocessor.
It can be seen that in the embodiment of the present disclosure, the identification of the human identity can be performed based on multiple attributes in the human image, and even under the condition that the distance between the image acquisition device and the human body is far, the identification of the human identity is favorably and accurately identified according to the multiple attributes in the human image, and further, the processing precision of the image of the sports field is favorably improved.
In one implementation, the plurality of attributes includes clothing color and text content; correspondingly, the identifying the multiple attributes of the human body image to obtain the identification results corresponding to the multiple attributes in the human body image may include: carrying out clothing color identification on the human body image to obtain clothing color information of the human body image; and performing text recognition on the human body image to obtain text information in the human body image.
After the clothing color information and the text information are obtained, the human body identity information in each human body image can be determined according to the clothing color information and the text information.
Here, the text content may be content with unique identification for distinguishing different person identities, and the text content may be numeric text, literal text, etc., where the literal text may be text such as name, code number, etc.
In a real scene, each human body image in the motion field can represent an image of at least one color, that is, color information of each human body image can be used for representing at least one color; illustratively, the color information of each human body image may represent a skin color, a hair color, a clothing color of the human body, wherein the clothing color may include one or more colors.
In the embodiment of the disclosure, after each human body image is obtained, each human body image can be processed to obtain a clothing region of each human body image; then, color information can be extracted from the clothing region of each human body image, and the color information of each pixel point in the clothing region of each human body image is clustered, so that the color information of each part in the clothing region of each human body image is determined. In one implementation, the above implementation process may be implemented by a pre-trained clothing recognition model, or other implementations may be adopted.
It will be appreciated that the clothing of persons in a sports arena will typically contain numerical text information such as numbers to indicate the identity of a person, although the clothing of persons in a sports arena may also contain other non-numerical text information such as names of persons, names of sponsors, etc.
The following exemplarily illustrates an implementation of text recognition for each human body image.
In a first implementation manner, text Recognition may be performed on each human body image by using an Optical Character Recognition (OCR) method to obtain text information in each human body image, and then, the text information may be extracted from the text information in each human body image. Here, OCR refers to a process of translating a shape into a computer text using a character recognition method; namely, the process of analyzing and processing the image file of the text data and obtaining the character and the layout information.
In a second implementation manner, a text recognition model trained in advance may be used to perform text recognition on each human body image, so as to obtain text information in each human body image. Illustratively, the text recognition model may be RCNN or the like.
The digital text information in each human body image can be used for representing the human body identity information, and the clothing color of the human body image can be used for distinguishing the category of the person in the sports field, so that the human body identity information in each human body image can be uniquely and accurately determined according to the clothing color information and the digital text information; illustratively, two parties of a match in a sports field are personnel in team D and personnel in team E, the clothing colors of the personnel in team D and the personnel in team E are respectively red and blue, the numbers of the personnel in team D are respectively 1 to 7, and the numbers of the personnel in team E are respectively 1 to 7, so that the category of a human body can be determined according to the clothing color information of each human body image; under the condition that the category of the human body is determined to be D team personnel, the human body identity information in the human body image can be uniquely determined according to the digital text information in the human body image, for example, the human body identity information of the human body image is No. 5 personnel in the D team personnel; and under the condition that the category to which the human body belongs is determined to be the personnel in team E, the human body identity information in the human body image can be uniquely determined by referring to the mode of determining the human body identity information of the personnel in team D.
As can be seen from the above description, the human bodies in each human body image can be automatically grouped according to the category to which the person belongs, based on the clothing color information of each human body image.
It can be seen that, in the embodiment of the present disclosure, the identification of the human identity can be performed based on the color and the number in the human image, and even when the image capture device is far away from the human body, the color and the number in the human image can be easily and accurately identified.
In the embodiment of the disclosure, after the at least one human body image is obtained, under the condition that the quality score of the first human body image in the at least one human body image is lower than the quality score threshold, the multiple attributes of the first human body image may be identified, so as to obtain the identification results corresponding to the multiple attributes in the first human body image. Wherein the first human body image represents one image of the at least one human body image.
For example, the garment color recognition may be performed on the first human body image and the text recognition may be performed on the first human body image in a case where the quality score of the first human body image is lower than the quality score threshold.
Here, the quality score of the first human body image may be represented by the number of pixels of the human body, the number of pixels in a partial region of the human body, or a distance from the human body to the image capturing device, and the quality score of the first human body image is positively correlated with the number of pixels of the human body or the number of pixels in a partial region of the human body and negatively correlated with the distance from the human body to the image capturing device.
It should be noted that, when the quality score of the first human body image is not lower than the quality score threshold, the human body identity of the human body image may be identified by a pedestrian re-identification method, a face identification method, or the like, so as to determine the human body identity information in the human body image.
In the embodiment of the disclosure, the quality scoring threshold may be set according to experience, or trial values may be performed on the quality scoring threshold, and for each trial value of the quality scoring threshold, under the condition that the quality score of the human body image for testing is not lower than the quality scoring threshold, it is determined whether the human body identity of the human body image for testing can be accurately identified by a pedestrian re-identification method, a face identification method, or the like, and then the quality scoring threshold is selected from the various values of the quality scoring threshold according to the determination result; here, the human identity information of each human body in the human body image for testing is known information so as to determine whether the human identity of the human body image for testing can be accurately identified.
It can be seen that, under the condition that the quality score of the image of the human body is lower than the quality score threshold value, the distance between the image acquisition equipment and the human body can be considered to be far, and for the condition, the human identity of the image of the human body can be accurately determined based on the colors and the numbers in the accurately identified image of the human body, so that the processing precision of the image of the sports field can be favorably improved.
Under the condition that the quality score of the image of the human body is not lower than the quality score threshold value, the image acquisition equipment can be considered to be close to the human body, and for the condition, the human body identity of the image of the human body can be accurately identified by adopting a pedestrian re-identification method, a face identification method and the like.
In an embodiment of the present disclosure, one implementation of determining that the quality score of the first human body image is lower than the quality score threshold may be: and under the condition that the number of the pixel points of the first target object in the first human body image is smaller than the set number threshold, determining that the quality score of the first human body image is lower than the quality score threshold.
Here, the first target object represents at least a part of a human body, for example, the first target object is a human body, a human face, a human hand, human clothing, or the like.
The following exemplarily explains a determination manner of the set number threshold.
In a first implementation manner, the set number threshold may be determined according to the quality score threshold, that is, after the quality score threshold is determined, an upper limit value of the number of pixel points of the first target object in the image of the human body is determined by taking that the quality score of the image of the human body is lower than the quality score threshold as a target, and then the set number threshold is determined, where the set number threshold is less than or equal to the upper limit value.
In a second implementation manner, trial value taking may be performed on the set number threshold, and for each trial value taking of the set number threshold, under the condition that the quality score of the human body image for testing is not lower than the quality score threshold, it is determined whether the human body identity of the human body image for testing can be accurately identified by a pedestrian re-identification method, a face identification method, or the like, and then the set number threshold is selected from the various values of the set number threshold according to the determination result.
