Effective recognition of objects calls for the appropriate selection of feature descriptor. In this paper, we generalize the "extended local ternary patterns" (ELTP) to form a novel and compact set of features named center-symmetric extended local ternary patterns (CS-ELTP). The newly defined CS-ELTP follows a simplified encoding procedure and has a lower dimension for a fixed neighborhood...
The performance of the mobile video broadcast is weakened when applying the traditional broadcast scheme which is forced to pick a single bit rate supported by the worst receiver. It leads to the drawback that receivers with better channels cannot obtain better video qualities. This paper proposed distributed Realcast, an analog video delivery scheme based on real value transmission, to provide differentiated...
Limited to the traditional digital transmission design which forces the source to pick a single bit rate supported by the worst receiver to transmit data, the mobile video broadcast service cannot provide better video qualities to the receivers with better channels. This paper proposes an analog coding and transmission scheme named Realcast to provide channel adaptive video broadcast service. It utilizes...
An appropriate search region is necessary for efficient multiview video coding (MVC). In this paper, the global disparity of two views is used to decide the size of the search region adaptively in the inter-view prediction of MVC. We first propose a simple method to obtain the global disparity vector (GDV) quickly, and analyze the relationship between the real disparity vector (DV) and GDV. It is...
In this paper, we propose a unified loop filter for high-performance video coding, which suppresses the quantization noise optimally and improves the objective and subjective quality of the reconstructed picture simultaneously. The proposed filter unifies nonlinear enhancement filter (for removing blocking and ringing artifacts) and linear restoration filter (for improving coding efficiency) within...
This letter proposes a unified loop filter for video coding, which suppresses the quantization noise optimally and improves the objective and subjective qualities of the reconstructed picture simultaneously. The proposed filter unifies nonlinear enhancement filter and linear restoration filter within the classical optimization framework of least mean square error. To adapt to locally diverse quantization...
In most of recent video coding standards based on block-based hybrid coding scheme, especially in the state-of-the-art H.264/AVC standard, motion vector information occupies a considerable portion of the whole compressed bitstream. Therefore, the efficient coding of motion vectors has become an essential objective to further reduce the bitrate. In this paper, we propose a novel motion vector coding...
