Image processing method, device and computer-readable storage medium

Abstract

The present invention provides an image processing method, device and computer-readable storage medium, including: determining the first coordinate in the preset area of ​​the target image; correcting the first coordinate according to the preset correction rule to obtain the second Coordinates: performing point cloud registration calculation on the first coordinate set and the second coordinate set to obtain correction parameters, and correcting the background area in the target image according to the correction parameters and the second coordinates to obtain a correction image. The correction parameter can make the registration and alignment of the background area outside the preset area and the background area of ​​the target image be achieved on the basis of retaining the trimming trace of the preset correction rule in the preset area. In addition, because the coordinates of the four corners of the target image are introduced in the process of obtaining the correction parameters, the coordinates of the four corners of the correction image are limited to be the same as the coordinates of the four corners of the target image, thus solving the problem of There is a problem of screen shaking during video playback.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an image processing method, device and computer-readable storage medium. Background technique [0002] With the development of mobile Internet technology, bandwidth tariffs are getting lower and lower, and live broadcast platforms have also exploded. Face-lifting and facial features beautification are common video beautification needs during live video broadcasting or video selfies. Therefore, fast, efficient, and stable beautification algorithms have good commercial value and application prospects. [0003] In the prior art, real-time beautification in live broadcast or video mainly adopts the method of image processing, and corrects the whole or local area of ​​each video frame image in the video, so that the corrected video picture can achieve the desired effect. Require. For example, in a video with a portrait image, the face area of ​​each video frame image i...

Problems solved by technology

[0005] In view of this, the present invention provides an image processing method, device and computer-readable storage medium, to a certain extent, solves the problem that the correction of the local area in the current solution will affect the background area outside the local area, so that the background area will be Unnatural deformation occurs with the deformation of the local area, and when the video is played, the position shift of the object in the screen will cause the background outline of the screen to shift accordingly, resulting in the problem of screen shake
