Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Since the multi-viewpoint color video coding does not fully utilize the human visual perception characteristic compression, there is a large amount of redundancy in the multi-viewpoint color video, so in order to further reduce the coding time of the multi-viewpoint color video without affecting the human visual perception , the present invention proposes a fast coding method for multi-viewpoint color video based on binocular just perceivable distortion, which calculates the corresponding binocular just perceivable distortion for the macroblocks in the right-viewpoint video before encoding the multi-viewpoint color video value to reduce encoding time for encoding multiview color video.

Abstract

The invention discloses a method for quickly coding multi-view color videos based on binocular just perceptible distortion. The method includes the first step of utilizing parallax error information the left view video and the right view video to determine a binocular just perceptible distortion value of each macro block within a non-boundary area in each frame of right view image in the right view video, and the second step of terminating macro block mode selection in advance according to the binocular just perceptible distortion value. On the basis of not causing rate-distortion performance degradation, the method for quickly coding the multi-view color videos can effectively improve coding efficiency of the multi-view color videos. The saved coding time can reach to 66.48% to 71.90%, and saves the coding time by 68.46% on average.

Description

technical field [0001] The invention relates to a method for processing multi-viewpoint color video signals, in particular to a fast encoding method for multi-viewpoint color video based on binocularly detectable distortion. Background technique [0002] 3D and free-viewpoint television make extensive use of multi-viewpoint color video for scene description. Multi-viewpoint color video includes multiple viewpoints in color, and after encoding, transmission, and decoding, virtual viewpoint rendering is performed on the display terminal. In multi-view color plus depth video, multi-view color video coding has been extensively studied, and the more applicable coding platforms include joint multi-view video model and joint multi-view video coding. However, because the research on the characteristics of human vision is developing, the use of the perceptual characteristics of the human visual system in the compression of multi-viewpoint color video needs further research.
