Comfortable Disparity Modification for Existing DIBR Systems

In recent year, 3DTV displays have become more popular in the consumer market. However, the visual discomfort is still the common problem when audiences view the stereoscopic 3D video for a long time period. Most of the discomfort comes from the excessive or improper disparity. To ease this problem, the comfortable disparity modification for existing depth-image-based rendering (DIBR) system is proposed in this paper. The proposed method contains several main parts such as degree-dependent algorithm, disparity range determination, and zero-parallax region based disparity remapping. To achieve customized 3D perception, a novel 3D adjustment mechanism is also proposed. Experimental results reveal that the proposed method can adjust the disparity effectively, which will be a great help for existing DIBR systems to generate comfortable 3D videos.
