Abstract: |
Disclosed is a method and device for realizing self-adaption quantization in encoding process. The mainly adopted implemental schemes comprise: firstly, based on the content of the encoding image, selecting a coincidental quantizing mode; secondly, in the decision-making process of the quantizing mode, adopting the encoding type, the motion vector, etc. of two adjacent blocks as the decision-making gist for the quantizing mode selection of the current block; finally, decision-making of quantizing mode also considering about the different sensitivity of human visual capability to different image content. Thereby, the present invention can make full use of human visual capability and can realize the great improvement on subjective quality of the encoding images in same encoding rate. |
