摘要
针对无线网络视频传输中遇到的图像质量问题,从应用层设计出合适的视频误码隐藏方案来提升画质,通过阐述基于误码后处理的加权内插算法,实验验证了算法的可行性,结果表明:加权内插算法对于提升无线传输视频效果明显,达到误码率6%以内的视觉标准。.
Wireless video transmission for image quality issues encountered, from the application layer to design appropriate programs to enhance video quality error hidden by elaborate post-processing based on error-weighted interpolation algorithm, experiments show the feasibility of the algorithm The results showed that： the weighted interpolation algorithm for wireless transmission of video effects improve significantly, to within 6% error rate the visual standard.
