In saliency based video coding, the salient parts of the each frame are encoded with higher quality than non salient areas to improve the signal to noise ratio and get higher compression ratio.In this paper, the background of the saliency based video perceptual coding technology is introduced first.Then the characteristics of motion, color and texture are extracted to form the saliency map.The quantization control in high efficiency video coding (HEVC) is incorporated with the visual saliency map to reduce the bit rate by adaptively changing the quantization parameter.Experimental results show that the proposed method can save the bit rate with improving the perceptual quality of regions-of-interest.
