Method for guiding multi-view video coding quantization process by visual perception characteristics

The invention relates to a method for guiding coding quantization process by visual perception characteristics. The method includes the following operating steps that (1) a brightness value of each frame of an input video sequence is read, and a just noticeable distortion threshold value model of a frequency domain is established; (2) prediction on each frame passing through the viewpoints and between the viewpoints in the input video sequence is performed; (3) residual error data are subjected to discrete cosine transform; (4) a quantifying step size of each macro block in the current frame is dynamically adjusted; (5) lagrangian parameters in a rate-distortion optimization process are dynamically adjusted; and (6) quantized data are subjected to entropy coding to form a code stream, and the code stream is transmitted through network. By means of the method, the video compression efficiency is improved under the condition that subjective qualities are basically unchanged, and the video is suitable for being transmitted in the network.
