文档介绍：摘要视频误码掩盖是一种有效的抗误码视频传输方法,它主要在解码端对存在误码的区域进行处理,根据周围有效像素点对丢失图像进行恢复。本毕业设计主要研究适用于 的帧内误码掩盖方法。本文首先介绍了 的标准采用的技术和相应的抗误码技术。对国内外部分资料的学****基础上, 提出了一种基于内容自适应划分的帧内误码掩盖方法,并通过 Matlab 语言加以实现,其中帧内误码掩盖程序的较好的 GUI 用户界面。仿真实验表明,本毕业设计实现的算法与双线性内插、方向内插方法相比, 掩盖后图像的主客观质量均有一定的提高。关键词: ;误码掩盖;视频编码;峰值信噪比 ABSTRACT Video error concealment is an effective method of error resilient video transmission . It is mainly to deal with missing region in the video decoder. Recovery the lost images according to the surrounding effective pixels. The Graduation Project mainly Research apply to frame error concealment method. In this thesis, we first introduce video coding technology and relevant error resilient techniques. Then based on the learning of the information abroad, we proposed a content-based adaptive error concealment method , and achieved through the Matlab language , frame error concealment procedure in which the better user interface GUI. Simulation results show that , compared with the Bilinear interpolation(BI), and the direction of interpolation(DI),the proposed algorithm have definitely improved with the conceal image subjective image quality .
