摘　　要：基于感知的视频编码方法是目前视频编码的研究热点。该文综合论述了基于感知的视频编码方法,重点阐述了基于感知的3维视频编码方法。首先,对目前利用人类视觉系统中的亮度、对比敏感度、中心凹等视觉感知特性的单视点视频编码方法进行分析并指出其存在的问题。然后,对基于立体感兴趣区域和双目敏感度特性的3维视频感知编码方法进行了分析和论述。最后,就基于感知的视频编码方法的进一步发展提出了若干技术与研究方向的展望。Recently, a great number of interests have been attraete~ to perc^p~u~ v,u ~ . - . perceptual video coding and especially perceptual three-dimensional video coding are reviewed. Firstly, single-view video coding is analyzed by utilizing perceptual characteristics of human visual system including luminance, contrast sensitivity, fovea, etc, and then their problems are analyzed. Secondly, the perceptual three-dimensional video coding based on the region of interest and binocular sensitivity characteristics are discussed and analyzed. Finally, several future research directions for this technology and research field are discussed.
