摘要
针对会话视频的严格的实时性要求,提出一种基于H.264/AVC会话视频的错误抵抗编方法;建立一种低复杂度的感兴趣区域分割算法;基于所提分割算法,对感兴趣区域进行长期参考帧预测编码,从而达到提高感兴趣区域的视频传输质量的目标.所提方法具有低复杂度的特点,能够满足会话视频的实时性要求,并且易于移植入H.264/AVC编码器.仿真结果证明了算法的鲁棒性和编码有效性.
It is also a challenge for transmission for conversational wucu u conversational video this paper, we propose a low-complexity error resilient coding scheme for H. 264/AVC communications. For the conversational video, the attention-attracted areas make more contributions to the perceptual quality for end users. Therefore, the proposed scheme combines the fast region-of-interest （ROI） segmentation and the long-term reference （LTR） frame coding in order to improve the perceptual quality of ROI areas. The scheme can be easily integrated into the H. 264/AVC encoder. Simulation results verify the robustness and coding efficiency as well as improved subjective visual quality.
