AI Technical Summary
Problems solved by technology
[0002] In the current technology, there is no method that can be directly used to detect the specific position of the screen in the video picture. It can only detect whether there is a screen in the video picture, or can only express the target screen through the minimum circumscribed matrix, that is Only the approximate location of the screen can be known, but the specific location of the screen cannot be known

The present disclosure relates to the field of AI, and in particular, to a method, an apparatus, a readable medium, and an electronic device for returning a screen in a video picture. The present disclosure adopts a preset network regression model to regress the coordinates of the four corners of the screen frame in the video picture, so as to determine the specific position of the screen appearing in the video picture. Among them, the BBox regression of the preset network regression model is used to return the coordinates of the four corners of the screen representing the four corners of the screen in a fixed order, that is, the expression of the preset network regression model for the target object is composed of the four corners representing the screen Four-corner frame, so that the preset network regression model can return the coordinates of the four corners of the screen frame in the video frame when it detects that the video frame contains a screen, and returns to the frame of the screen in combination with the feature that the screen is a rectangle, thereby Determine the exact location of the screen that appears in the video frame.
Description
technical field [0001] The present disclosure relates to the field of AI, and in particular, to a method, an apparatus, a readable medium, and an electronic device for returning to a screen in a video picture. Background technique [0002] In the current technology, there is no method that can be directly used to detect the specific position of the screen in the video picture, only whether there is a screen in the video picture can only be detected, or the target screen can only be represented by the minimum external matrix, that is, Only the approximate position of the screen can be known, but the specific position of the screen cannot be known. SUMMARY OF THE INVENTION [0003] This Summary is provided to introduce concepts in a simplified form that are described in detail in the Detailed Description section that follows. This summary section is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to be used t...
