Embodiment 1

[0039] refer to Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a method applicable to various non-rectangular section screen capture methods, including:

[0040] S1: Construct a deep confidence multi-shape screenshot model based on the principle of least squares support vector machine. It should be noted that building a multi-shape screenshot model includes:

[0041] Use the least squares support vector machine to select the radial basis function as the objective function of the multi-shape screenshot model, as follows:

[0042]

[0043] Among them, x={x 1 ; x 2 ;…;x 14}: screenshot feature matrix composed of historical screenshot mode feature vectors collected based on deep belief network, y: screenshot feature vector and touch point information of historical screenshot mode, σ: kernel width, reflecting the distribution and range characteristics.

[0044] S2: Optimizing the training of the multi-shape screenshot model by using...

Embodiment 2

[0067] In order to better verify and explain the technical effect adopted in the method of the present invention, the present embodiment chooses to carry out a comparative test with the traditional Word document screenshot method and the method of the present invention, and compares the test results by means of scientific demonstration to verify that the method of the present invention has real effect.

[0068] The traditional Word document screenshot method is cumbersome to operate, not efficient, and affects user experience. In order to verify that the method of the present invention has higher operating efficiency, real-time accuracy of screenshots and better user experience compared with traditional methods, in this embodiment The real-time measurement and comparison of 100 randomly selected user operations will be carried out by adopting the traditional Word document screenshot method and the method of the present invention respectively.

Abstract

The invention discloses a method applicable to screen capture of various non-rectangular sections, and the method comprises the following steps: constructing a deep confidence multi-shape screenshot model based on a least square support vector machine principle; performing optimization training on the multi-shape screenshot model by using an optimal iterative strategy, and importing the trained multi-shape screenshot model into a screenshot mode; selecting the screenshot mode at a position to be subjected to screenshot, and triggering the multi-shape screenshot model to run a touch point received on a detection screen; when the number of the touch points is greater than a set threshold value, determining a screenshot range and a screenshot shape according to the number of the touch pointsand the positions of the touch points on the screen so as to carry out screenshot. According to the method, the number of the touch points can be accurately obtained under various scenes so as to carry out operation of screenshot of various shapes, the real-time performance and applicability of screenshot can be guaranteed while complex scene conditions are met, and the wide applicability and userexperience of screenshot are improved.

Description

technical field [0001] The invention relates to the technical field of computer screen shots, in particular to a method suitable for taking pictures of various non-rectangular cross-sectional screens. Background technique [0002] Most of the existing mobile terminals have a screenshot function. Users can trigger the screenshot function of the mobile phone to capture pictures and store or share them. However, the current screenshot function is limited to full-screen screenshots, that is, only the entire screen can be captured, and accurate screenshot results cannot be obtained. The operation is not flexible and convenient enough, and the user experience is not good. [0003] In the current screenshot method, the cross-section of the picture is usually rectangular. The method of taking the picture is as follows: ① take any two points on the screen as point A and point B; ② take the virtual line segment formed by point A and point B as Diagonal line; ③The horizontal, flat and...
