Abstract
The present embodiments include methods, systems, and apparatuses for foreground biased depth map refinement in which horizontal gradient of the texture edge in color image is used to guide the shifting of the foreground depth pixels around the large depth discontinuities in order to make the whole texture edge pixels assigned with foreground depth values. In such an embodiment, only background information may be used in hole-filling process. Such embodiments may significantly improve the quality of the synthesized view by avoiding incorrect use of foreground texture information in hole-filling. Additionally, the depth map quality may not be significantly degraded when such methods are used for hole-filling.
