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...
