Abstract

The invention relates to the technical field of image processing, and provides an image encoding method and device. The method includes: firstly, obtaining image quantization parameters of the image to be encoded; secondly, performing edge detection on the image to be encoded to obtain edge information of the image to be encoded; macroblock quantization parameters corresponding to each macroblock; finally, the image to be coded is coded according to the macroblock quantization parameter corresponding to each macroblock to generate a coded image. Compared with the prior art, the image coding method and device provided by the present invention can solve the problem of excessive edge compression and blurred edges in the prior art.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image coding method and apparatus. Background technique [0002] In the field of communication, the transmission bandwidth is often a very important resource. In order to ensure the transmission of video data, in video coding, it is necessary to obtain the optimal image quality under the limited condition of a certain transmission bandwidth, and the coding control of the encoder is required. have certain requirements. [0003] In the existing video coding rate control methods, in order to make the output bit rate of the video more accurate during the encoding process, the bit rate is usually controlled to the macro block, but at the same time the accuracy of the bit rate is improved, it will cause a frame of image The result of uneven quality makes the subjective effect of the image weaken and the viewing effect is not good. The main facto...
