In this paper, we propose an efficient scheme to automatically convert existing 2D videos to 3D ones. The proposed method extracts motion information from two consecutive frames to estimate depth map for each of them. In the method, we first develop a region-based Graph cut method to fast and accurately perform motion segmentation, which is robust to large interframe motions. Then, a depth assigning...
The performance of Distributed Video Coding (DVC) has a great reliance on the accuracy of side-information, which is estimated according to the intra-coded key frames that are assumed to be reconstructed lossless in this paper. A novel content-based side-information generation approach is proposed to improve the Wyner-Ziv frame estimation. First, the motion features and texture features are extracted...
Summary form only given: In all existing codec designs for asymmetric Slepian-Wolf coding (SWC), it is assumed that the source sequence is i.i.d and equiprobable. When it comes to more complex source statistics, the encoder should firstly remove the redundancy within the source. However, this increases the complexity of the encoder. In this paper, we propose an asymmetric SWC scheme which explores...
Apply fractal transform to digital image compression arithmetic to obtain tremendous compression ratio on the basic of retaining rebuilding image quality, and raise the improvement method base on entropy arrangement algorithm for the disadvantage of slow fractal arithmetic coding. The experiments have shown that the improvement method encoding time is about twenty times faster than the traditional...
