Problems solved by technology

However, as the content of image data continues to enrich, when processing a certain frame to form a complex image, only by fixing one codec algorithm, the image codec effect will not meet the expected settings, such as based on the image data of the target frame , to synthesize another frame of image on top of the target image; for this type of image, if the JPEG encoding device is used alone or the PNG encoding device is used, because the encoding and decoding requirements corresponding to all macroblocks in the image cannot be taken into account, the image compression effect will be caused Does not meet preset requirements

Abstract

The invention provides an image processing method and system, relates to the field of image processing, and the image processing method and system can improve the effect of image encoding and decoding. According to the specific technical scheme, the method comprises steps of obtaining a target image and parameter information corresponding to the target image through an encoding device, dividing the target image into at least two image layers, and then determining a target encoding algorithm corresponding to each image layer according to the parameter information of each image layer; and encoding each layer according to the target encoding algorithm to generate an encoded target image. And transmitting the coded target image to a decoding device, decoding the target image layer by the decoding device by determining a coding algorithm corresponding to each image layer, and generating a decoded target image according to each decoded target image layer. The method is used for image encoding and decoding processing.

Description

technical field [0001] The present disclosure relates to the field of electronic information technology, and in particular to an image processing method and system. Background technique [0002] With the rapid development of image processing technology, in order to better transmit images, images will be encoded and decoded. In the prior art, when encoding and decoding an image, a corresponding encoding and decoding algorithm will be adopted according to the data characteristics of the image. For example, for a natural image with rich colors but no sudden changes in color, the compression effect of JPEG is better than that of PNG. The compression effect of the encoding device is good, and for computer-synthesized images with relatively simple colors, the compression effect of using the PNG encoding device is better than that of using the JPEG encoding device. However, as the content of image data continues to enrich, when processing a certain frame to form a complex image, o...
