Abstract: Intermediate view synthesis is a key technique to realize interactive stereoscopic display. The viewer can obtain a “look around" perception from a synthesized virtual view image by changing the viewpoint. This paper proposes an intermediate view synthesis algorithm based on image mosaic to create the virtual view image by exploiting view interpolation and morphings. The original stereo pairs are first normalized to reduce luminance difference. Based on the asymmetry in the left and right camera views, credible areas are chosen to create the transitional view, exploiting the disparity information. Intermediate view images are created by combining view interpolation and morphing. Experimental results show that the proposed method can provide satisfactory rendering results with lower computation load based on objectbased processing, which can be used in interactive stereoscopic display in video conferencing.
