| 摘 要： | 基于特征点视差估计与三角网格映射,提出一种立体图像压缩编码算法。为了保持压缩后视点对的视差不发生变化,利用绝对差值图进行特征点选取。进行残差图像编码时,结合了心理立体视觉影响、人眼亮度色度特性、立体图像对色度特点与三角网格映射特点等因素,提出了立体残差编码只需对Y分量进行的方法。实验表明,该算法具有一定的优越性,如压缩比大,图像质量与立体感均较好。

| Abstract: | A stereo image coding algorithm is proposed based on disparity estimation of feature points and triangle mesh mapping.To maintain the disparity of two view-points after coding,the feather points with the absolute disparity image are extracted.When coding from the residual pictures,the stereo residual coding is conducted only in Y vector based on the influence of the psychological stereo perceive,luminance and tint feature of human eyes,the tint feature of the stereo image pair and feature of the triangle me... |
