Image processing method and device and computer readable storage medium

Abstract

The invention provides an image processing method and device and a computer readable storage medium, and the method comprises the steps: determining a first coordinate in a preset region of a target image; according to a preset correction rule, correcting the first coordinate to obtain a second coordinate; and performing point cloud registration calculation on the first coordinate set and the second coordinate set to obtain a correction parameter, and correcting a background area in the target image according to the correction parameter and the second coordinate to obtain a corrected image. The correction parameters can achieve the purpose that the background region outside the preset region is registered and aligned with the background region of the target image on the basis that the correction trace of the preset correction rule is reserved in the preset region. Besides, the coordinates of the four corner points of the target image are introduced in the process of obtaining the correction parameters, so that the coordinates of the four corner points of the correction image are limited to be the same as the coordinates of the four corner points of the target image, and the problem of image dithering in the video playing process is solved.

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
