摘要: Depth-image-based rendering (DIBR) is the key technology in a 3DTV system, which generates two or more virtual view images from 2D color image and its associated per-pixel depth image. The most troubling problem DIBR appearance of holes images, are called “disocclusion”. To remove newly exposed regions, this paper, we propose novel approach to synthesize images. First, pre-processed by an adaptive edge-dependent asymmetric smoothing filter. Secondly, horizontal displacement pixels, as result 3D warping, obtained based on non-linear transformation values distances. experimental results show that proposed method can efficiently reduce completely disocclusion no geometric distortion arises.
