Dithering processing method and apparatus of key points

Abstract

The invention relates to a dithering processing method and apparatus of key points. The method includes steps: detecting a plurality of first key points of a current frame image in a video streaming,and obtaining detection position coordinates of the plurality of first key points; obtaining first shape topology structure information corresponding to a previous frame image in the video streaming,and obtaining identification information of the key points capable of being connected to edges in the plurality of first key points of the current frame image; and determining target position coordinates of the plurality of first key points according to the detection position coordinates of the plurality of first key points, the first shape topology structure information and the identification information, and moving the plurality of first key points to the target position coordinates. According to the method and apparatus, the dithering problem of the key points in the video streaming can besolved, the positioning precision of the key points in the video streaming can be improved, and the vision delay sense of the key points can be reduced when a to-be-detected object in the video streaming moves.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a key point shaking processing method and device. Background technique [0002] With the continuous development of science and technology, the application of object key point detection technology is becoming more and more extensive. For example, the expression stickers based on face key point detection technology are more popular at this stage. At present, in the same video stream, based on this technology, the positions of the key points detected by the terminal device in the front and back frames of the video stream will be different, so that all the key points detected will randomly shake in the video stream Phenomenon, resulting in application products based on object key point detection technology cannot be used normally. Therefore, how to solve the shaking of key points in the video stream is an urgent problem to be solved by those skilled in the art. [0003] In the tradit...

Problems solved by technology

[0004] However, using the above-mentioned traditional technology will result in low position accuracy of the key points, and there will be a problem that the key points move slowly when the object moves
