  • Abstract
    View synthesis is one key enabling technology for free-viewpoint television (FTV). It uses multiple image frames and depth maps to generate the intermediate view at nearly any arbitrary viewpoint. In our proposed 2-stage algorithm, we adopt triangular warping with a new feature point extraction scheme for the first texture mapping stage. The new feature point extraction scheme uses the correlation between the image luminance gradients and the depth map. In the second stage, we use the median filtering and the multi-band blending technique to reduce the artifacts on the image object boundaries caused by the discontinuity and the imperfection of depth maps. Experimental results show that our proposed method produces better visual quality in comparison with a latest view synthesis algorithm.
