**Boundaries**

Due to imperfect depth maps, a degradation artifact is particularly notably around object boundaries. This is derived from a texture-depth misalignment whose apparition is consequence of techniques of capture and processing of 3D-images and must be supressed as much as possible.

Y. Zhao proposes a novel solution of suppression of misalignment and alignment enforcement between texture and depth to reduce background noises and foreground erosion, respectively, among different types of boundary artifacts.
