Description

Method and device for identifying painting brush style by using safety Zhuo Huatu software
Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for identifying a painting brush style by using software of An Zhuo Huatu.
Background
With the popularization of commercial display and touch televisions, android drawing software designed for large screens of commercial display and touch televisions is also increasing. The functions of drawing lines, changing the color of the drawing lines, changing the thickness of the drawing lines, or changing the strokes of the drawing lines, etc. are all developed around one of the core functions of the android drawing software.
In the prior art, the color, thickness, stroke, transparency and the like of the drawn lines can be modified, so that the drawn lines have different 'patterns', but the modification of the patterns is usually aimed at a whole single user. However, a large screen such as a commercial display and a touch television has a use scene in which multiple users draw lines on the screen at the same time. It is also true that in this case, each simultaneously operating user is given the same style. However, if the user is given one more choice, each user operating at the same time can draw the line of the exclusive style, the user experience is better.
In order to realize the result, a set of pens with different widths can be provided for users when commercial display and touch televisions are sold, and the built-in android drawing software is used for distinguishing the users operating simultaneously according to the touch widths obtained when the pens touch the touch screen and the preset touch widths.

The embodiment of the disclosure can be divided into a multi-stage calibration module, a multi-stage pattern selection module and a multi-stage identification module based on the acquisition and calculation of touch events.
In practical applications, only two stages are generally calibrated, generally referred to as the 1-stage is the thin pen and the 2-stage is the thick pen. More stages can be opened according to the requirements of clients, and the names of the stages can be set according to the preference of the clients. The screen is calibrated by having a light gray transparent circle in the middle of the screen, which is used for guiding the user to touch the screen with different gestures, and the circle can be displayed in different places after clicking each time, so as to guide the user to touch the screen with different gestures. The number of times of each calibration is also configurable, such as 10 times, although it is also arbitrary to change the profile to 30 times if the customer has a demand.
The multi-stage style selection module can switch and select the grade 1 or grade 2 painting brush style, can select the painting brush type, can select different painting brush types, can select thickness and color, and can also have more style settings such as transparency, granularity and the like.
The specific implementation method of the embodiment of the disclosure is described as follows:
as shown in fig. 2, the implementation process of the multi-stage calibration module specifically includes:
1. a multi-level recognition level N is selected (different sets of drawing patterns are divided into N sets according to different widths of the brushes when drawing lines).
2. And if N is 1, ending the calibration, and if N is more than or equal to 2, carrying out N rounds of data acquisition.
3. Each round of calibration corresponds to a level of data acquisition, and the level goes from low to high, corresponding to a thin to thick width. The first round, level 1 data acquisition, is taken as an example.
a. The software will then prompt the user that this is a level 1 calibration round and guide the user through multiple touches of different gestures with the same object.
a-1. Since one object is touched with different gestures, the touch area thereof is different. Taking a pen as an example, the different gestures can be understood as the angle formed by the pen and the screen, the pen point is one area when falling perpendicular to the screen, the pen point is another area when falling at 45 degrees with the screen, and the pen point is another area when falling at 10 degrees with the screen. Considering that when a user uses the device normally, it is common for the user to have different gestures, and the gestures are different in area but all need to be classified into one type or one level, so that data of touches with different gestures need to be collected for subsequent calculation.
b. The collected touch area set to level 1 is denoted as S 1 . (analogically, level 2 is S 2 Grade N is S n )。
4. After the calibration is finished, S is obtained 1 、S 2 、...、S n
5. According to S 1 、S 2 、...、S n Whether the requirements are met or not is judged by whether the requirements are met or not, such as whether the data are concentrated enough or not, whether the intersection parts of adjacent sets exceed the fault tolerance range or not, and the like, and other standards.
6. If the user does not meet the requirements, a friendly prompt is popped up, and the user is recommended to use other objects as line drawing tools or the multi-level recognition level is reduced.
7. If the data meets the requirements, calculating a demarcation value according to the adjacent sets, and marking the demarcation value as D n-1 In S form 1 、S 2 For example, the boundary value D is calculated 1
567-1. First, it is determined whether or not the intersection of the current aggregate set and the aggregate set one level lower than itself exceeds the fault tolerance range. The criterion is to take the maximum value in the aggregate one level lower than itself (if S 1 Corresponding to 0), the current set S is calculated n If the element duty ratio is larger than C1 (the first threshold value), the data is considered to be unsatisfactory, and the process proceeds to 6. Otherwise, 567-2 is entered.
567-2, determining if the data is sufficiently focused.
a. The variance σ of the current set is calculated, and if σ is greater than C2 (the second threshold degree described above), then the data is considered to need further refinement.
b. Calculating the variance sigma of the aggregate after removing the current maximum 1 Variance sigma after the current minimum value is removed by the aggregate 2 Judging sigma 1 And sigma (sigma) 2 The size is taken as the simplifying basis of the aggregation, and a new aggregation is obtained. For example, if sigma 1 Smaller means that we have removed and concentrated the current maximum, resulting in a new set.
c. And calculating the variance sigma of the new set, and if sigma is larger than C2, considering that the data needs to be further simplified. And continuing to execute b.
d. If σ is equal to or less than C2, the data compaction is considered to be completed (considering the worst case, only one compaction is left, the condition that d is always satisfied enters e.)
e. And calculating the percentage of the removed data in the process of changing the original collection into the simplified collection to be the original collection, if the percentage is larger than C1, considering that the data is not satisfactory, entering 6, otherwise, entering 7. ( And (3) injection: entering 7, the original set before simplifying is used as temporary judgment )
567-3 calculating a demarcation value D 1
a. Calculate set S 1 Average value A of (2) vg1 Assign it to P left Calculate S 2 Average value A of (2) vg2 Assign it to P right
b. Through (P) left +P right ) (2) obtaining P tmp
c. Calculation S 1 Is greater than P tmp The duty ratio of the data of (2) is calculated S 2 Less than P tmp Is a duty cycle of the data of (a). If the duty ratio of both the two sets is less than or equal to C1, the value is given to D 1 Obtaining a demarcation value D 1 . If not, enter D, find D by dichotomy 1 .
d. If a certain duty ratio is larger than C1, taking P (or one of P) close to another collection for subsequent processing, and if P is larger than C1, assigning P to P right ’,P tmp Assignment to P left '. Otherwise, assign P to P left ' assign to P right '. Then calculate P tmp ’=(P left ’+P right ' s/2, P tmp ' assign value to the P tmp And returns to the step c. (because of the front faces 567-1, 567-2, the case where the duty ratio of both the two pools is larger than C1 does not occur at the same time)
For example, we calculate S 1 That is S 1 Is greater than P tmp If the duty ratio of the data is larger than C1, we get closer to another set, namely S 2 P of (2) is defined according to our progression from thin to thick, that is S 2 Is larger. Plus we are to P left And P right Assignment of P right Is a ratio P left Larger, so is closer to S 2 P of (2) is P right
e. Repeating b.c.d. eventually always find D 1
8. By calculation, D is obtained 1 、D 2 。。。。。。。
9. And (5) successful calibration, and completing the calibration.
As shown in fig. 3, the process of the multi-stage style selection module specifically includes:
1. and providing a corresponding style selection interface according to the success level of the last multi-stage calibration module.
2. And selecting a corresponding series on the interface, and entering a style selection interface of the corresponding series (for example, the last successful grade is 3, and 1,2 and 3 are included in the three series).
3. Patterns with adjustable corresponding series number, including width, color, transparency, strokes, primitive painting points and other customized pattern effects, and recording the patterns corresponding to the corresponding series number as Y 1 ,Y 2 ,...,。
As shown in fig. 4, the process of the multi-stage identification module specifically includes:
1. when an object touches, when an action_pointer_down event occurs (action_pointer_down represents a touch event when one object is pressed), the number of stages is determined based on the touch area recorded by the touch event being recorded as area, and the POINTER (POINTER is a value used by android to indicate to which finger/object a single touch event belongs) is recorded.
2. The judging method comprises the following steps: if area < D1, the level is 1, and if D1 is less than or equal to area < D2, the level is 2 n-1 The number of the area is less than or equal to N.
After judging the number of levels, the line drawn by the touch event corresponding to the post-PointerID uses the pattern of the number of levels, for example, if the number of levels is judged to be 2, pattern Y is used 2
The embodiment of the disclosure is based on the touch area interval, allows drawing with different painting brush styles at the same time, solves the problem of different touch area standards reported by different touch frames through the calibration module, and avoids the limitation of needing to use a customized touch pen.
It should be noted that the steps illustrated in the above-described flow or flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.
