Abstract�� Traditional view interpolation can only synthesize the novel view along the base line. The proposed method based on triangular re-projection can iteratively divide the scene into consistent and inconsistent triangles given a few of initial matches, and implement free-viewpoint view synthesis by re-projecting these two groups of triangles in different strategies. The straight line constraint was introduced to direct the division along the line in order to reduce the discontinuity nearby the common side of two adjacent triangles. The new matching points were confirmed by the designed evaluation function in a special searching order. They were detected in the inconsistent regions for further division to produce more and more consistent regions. The color-image experiment proves that this method is effective to synthesize a photo-realistic image under wider changes in viewpoint.
