| Popis: | 103 An improved whole frame error concealment method for multiview video with depth is designed previously in the proposed thesis. The thesis includes three modification parts. First, the erroneous 1-to-1 pixels are concealed by the pixels from another view. The light differences between views are taken care by the information of motion vector of the projected coordination, and a reverse DIBR (Depth image based rendering) procedure. These procedures are based on assumptions that are better than the assumptions made in a state-of-the-art whole frame loss method for multiview video with depth. Second, the generation of the many-to-1 pixels is improved with their depth information. Third, the main point of this thesis, the hole pixels are found using the estimated motion vectors, covered by the mask and use the matrix multiplication to calculate the estimated motion vector. The experiment results show that compared to the state-of-the-art method, the combined system of three proposed methods is better, and improve the performance by 5.12 dB at maximum. |
