Abstract

Embodiments of the present invention provide an inverse filtering method, device, and electronic equipment. By selecting reference pixel points along the diagonal direction of each edge pixel point in the pixel matrix, a pixel group is established, wherein the edge pixel points include A matrix row and a matrix column at the edge of the pixel matrix; each pixel group is arranged in the order of the edge pixels to form a pixel sequence; each pixel group is calculated sequentially according to the pixel sequence, and the pixel value of each pixel point is calculated in parallel in each pixel group. In this way, through the establishment of pixel groups and pixel sequences, serial calculations are implemented in the pixel sequence parts, and parallel calculations can be implemented in the pixel groups due to decoupling. The combination of parallel and serial calculations can effectively improve the efficiency of inverse filtering. .

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an inverse filtering method, device and electronic equipment. Background technique [0002] Image processing usually uses a computer to perform denoising, enhancement, restoration, segmentation, feature extraction and other processing on the image to make the image meet the needs of actual use. Take PNG (English: Portable Network Graphics, Chinese: Portable Network Graphics) image processing technology as an example. PNG image is a lossless data compression image format that allows the use of palette technology and supports the storage of a single raster image with any color depth. And it has the characteristics of alpha channel (translucency), supports gamma correction, supports interlacing, and has nothing to do with the platform. The processing of PGN images usually includes steps such as file decompression and inverse filtering. Among them, file decompression is to ...
