Temporally recursive robust detail reconstruction from stereo 3D sequences

Current HD and 3D TV sets still have to cope with various input content resolutions that have to be displayed in native Full HD or higher resolution. Typical up-scaling methods only make use of spatial information in order to compute a high resolution output. Most of these methods show a low ability to reconstruct high frequency details. In this paper a method for reconstructing details from multiple input frames of a Stereo 3D sequence and generating a high detail output is presented. Utilizing temporally recursive processing, a memory efficient method is realized, which can be used for detail level enhancement post-processing in current 3D TV sets. Due to internal reliability estimation for motion and disparity vectors, the proposed method shows a high robustness against artifacts from erroneous motion and disparity compensation.
