Abstract

The invention provides a video coding method and a coder. The method comprises the following steps: (1) dividing the picture to be coded into an attention area and a background area; (2) and in the coding process, allocating a first coding resource to the attention area, and allocating a second coding resource to the background area, wherein the first coding resource is more than the second coding resource. The invention can optimize the performance of the video coding, reduce the complexity of computation for searching, and solve the technical problem that different picture areas can not be coded in different ways according to the actual demands in the prior art.

Description

technical field [0001] The present invention relates to video processing technology, in particular to a video encoding method and encoder. Background technique [0002] Inter-frame predictive coding is to use the correlation between video image frames, that is, time correlation, to achieve the purpose of image compression. It is widely used in compression coding of ordinary TV, conference TV, video phone, and high-definition TV. Using inter-frame predictive coding does not directly transmit the pixel value of the current frame, but transmits the difference between x and the corresponding pixel x' of the previous or subsequent frame, which can achieve a higher data compression ratio. [0003] Inter-frame predictive coding with motion compensation is one of the key technologies of video compression, and the motion estimation method often used in actual implementation is block matching method. It divides the image into many sub-blocks, and considers that the displacement of al...
