Abstract

The present disclosure relates to an image processing method, device, and storage medium. The method includes: for each target image block to be predicted in a target image frame, acquiring a reference pixel point of the target image block; according to the reference pixel point , a preset matrix, and a pre-trained offset corresponding to the target image block, and obtain the prediction result of the target image block; according to the prediction result of each of the target image blocks, obtain the corresponding The predicted image frame of . Therefore, the beneficial effect of improving the offset accuracy of the intra-frame prediction during image processing, and further improving the accuracy of the intra-frame prediction result is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method, device and storage medium. Background technique [0002] Generally speaking, for an image, the brightness and chrominance values ​​of two adjacent pixels are often relatively close, that is, the color changes gradually, and will not suddenly change into a completely different color. The purpose of video coding is to use this correlation to perform compression. Intra-frame prediction is to use the correlation of the video spatial domain to predict the current pixel by using the adjacent encoded pixels in the same frame image, so as to effectively remove the redundancy of the video spatial domain. [0003] Among them, the intra-frame prediction technology MIP (Matrix Weighted Intra Prediction, matrix weighted intra-frame prediction), its original idea comes from the intra-frame prediction technology based on neural network, that i...
