Artifacts exist in stereo correspondence. Object boundary artifact is one of the most difficult problems. The object boundary pixels receive colors from both foreground and background thus leads to wrong mapping. The occlusion fill-up process causes object boundary expansion which makes boundary pixels unreliable. We propose a boundary matting technique based on natural image matting algorithms to calculate the alpha value of the boundary pixels. Depth values which are suggested by alpha values can be recalculated. The limitation of matting algorithms is that they define only boundaries between two layers and cannot solve the multiple-layer definition problem. Our contribution is the localized methods of boundary matting which can solve the multiple layer boundaries in complex depth map. Our goal is superior view synthesis from stereo, thus the quality of virtual views are valued in experiments. The result shows that our technique reduces the boundary artifacts effectively.]]>Ruzinoor, C.M., A.R.M. Shariff, A.R. Mahmud and B. Pradhan,20111132473257Sharma, G., L. Baoku and W.
