Abstract: What properties the homography should have when the camera rotates around its optical center was discussed. Then combining these properties with the 3D image warping technique, a new way to synthesize novel views when camera rotates around its optical center was proposed. The method first generated part of the novel view by making use of the properties of the homography, and backward mapping method was used to avoid holes; then 3D image warping method was applied to create the remaining part of the novel view; finally, holes in the remaining part which were caused by 3D image warping were filled. Experimental results show that the proposed method provides novel views with quite good image quality.
