Depth-Image-Based Rendering (DIBR) has been regarded as the most promising solution for 3D TV, but exposure of occlusion areas that will lead to poor visual quality of synthesized virtual-view images is its inherent disadvantage. In previous studies, an asymmetric Gaussian low-pass filter with strong strength has been used to reduce numbers and sizes of disocclusion areas in synthesized images for improving visual quality. However, it also attenuates depth resolution seriously. DIBR should have a good compromise between improving visual quality and preserving depth resolution. In this paper, the factors inducing poor visual quality and attenuate depth resolution are addressed, and how these factors influence one another is analyzed as well. Based on the analysis results, a parallax-map-based DIBR system without soothing depth-images is proposed. Experimental results show that the proposed DIBR system can improve visual quality and preserve depth resolution well within normal depth preferences of viewers.
