在H.264/AVC标准中,当出现数据包丢失或缺损时,在解码端进行误码掩盖是一种经济而有效的保证视频质量的方法,因而广受关注。常见的做法是利用正确接收的时域或空域信息对误码区域进行掩盖。然而,对于误码率很高的视频,目前尚无令人满意的技术。该文中提出一种基于无迹Kalman滤波,并辅以改进的双线性插值的新型误码掩盖架构。对若干典型视频的高误码掩盖实验表明,其峰值信噪比高于边界匹配算法和传统双线性插值算法达4dB。 In the H.264 / AVC standard, wide attention has been paid to error concealment at the decoding end as an economical and effective way to guarantee video quality when packet loss or loss occurs. It is a common practice to mask the bit error region using correctly received time or space information. However, there is currently no satisfactory technology for video with a high bit error rate. In this paper, we propose a novel error concealment architecture based on non-trace Kalman filtering, which is complemented by improved bilinear interpolation. High bit error concealment experiments on several typical video show that the peak signal to noise ratio is higher than the boundary matching algorithm and the traditional bilinear interpolation algorithm up to 4dB.
