Based on algorithm for extracting video objects in one view-channel

a new scheme of extracting video objects in multi-view coding is proposed.A disparity estimation algorithm based on multi-level block matching is proposed.Moravec operator is used to find out characteristic disparity vectors in disparity images for precision confirmation.If a characteristic disparity vector is not precise enough

the block it belongs to will be matched again around the area indicated by the vector.If a block is still not matched precisely

it is split into four equal sub-blocks for block matching.Compared with traditional block-matching based algorithm

more precise and smooth disparity field can be acquired with the proposed algorithm

so that the quality of reconstructed image can be greatly improved.
