摘要
提出了一个视频编码框架,将双向塔式算法应用于视频编码之中,以提高在不可靠网络环境中视频传输的鲁棒性。根据视频编码特点,对双向塔式算法在采样策略、边缘增强、简化计算三个方面做出改进。实验表明,通过对算法的改进,提高了图像恢复质量,减少了时间开销,双向塔式算法应用于视频编码是可行的。
To improve the robustness of video transmission over networks, duplex pyramid algorithm was applied to video coding, and then a frame of video coding was proposed. Furthermore, to improve quality of images and reduce time cost, duplex pyramid algorithm was ameliorated in sampling, edge enhancement and reducing computation. Experimental result proved the feasibility of this application.
