摘要
在H.264/AVC视频标准中,去块滤波可以有效去除图像量化后的方块效应。但其复杂度较高,对去块滤波的优化成为编解码算法中的优化重点。该优化设计应用在基于TI公司TMS320DM6437处理器的实时标清H.264编解码软件中除了通过对算法本身特别是滤波强度判断部分的优化,还利用达芬奇平台的特点提出了整套优化方案。测试结果表明,在不影响图像质量的情况下优化效果有明显提高。
In H.264/AVC codec standard,deblock filter can reduce the block artifact.Because it is very complicated,optimization of the deblock filter is one of the key points of the H.264 codec＇s optimization.The design is one part of the real-time H.264 standard-definition codec software based on TI-TMS320DM6437.Except for the optimization of the block strength＇s judging,the design offers a whole optimization plan by the feature of Davinci platform.Simulation result demonstrates high efficiency of the plan under the same PSNR.
