| Summary: | 碩士 === 國立東華大學 === 電機工程學系 === 102 === This thesis proposes an effective error concealment algorithm of whole frame loss on color information for three-dimensional video encoding and transmission. Based on the motion vector extrapolation of previous reference frame, the depth-assisted algorithm can provide better error concealment result. The first part of this thesis is to pre-process Intra block of previous reference frame. The motion vector is set to zero for the previous literature. We give the appropriate motion vector for the Intra block of previous reference frame by utilizing the surrounding motion vectors and the corresponding depth information. The second part of this thesis is to propose a new motion vector selection algorithm on error frame according to the depth and extrapolated motion vector information. Experimental results show that the proposed algorithm provides better subjective and objective video qualities than the previous literature.
