摘　　要：在分析空间和时间二维插值去隔行算法特点的基础上,提出一种基于H.264编码的运动及纹理自适应去隔行算法。对H.264编码过程中的运动估计、运动补偿和帧内预测结果进行研究,将视频序列划分为运动区域、静止纹理复杂区域和静止纹理简单区域,分别采用沿自适应插值、竖直时域滤波和行平均插值方法进行去隔行处理。实验结果表明,该算法在处理运动区域和静止区域图像时,能有效抑制由于运动检测失误造成的梳齿和虚影问题,提升图像质量。This paper analyzes both the spatial and temporal interpolation methods and proposes an efficient new motion and texture adaptive de-interlacing algorithm based on the H.264 encoding.The picture is classified into three regions： motion region,static texture region and static smooth region based on the analysis of motion estimation,motion compensation and intra-prediction.Methods of ELA,VT and LA are used to do the region de-interlacing work.Experimental results show that the proposed algorithm works well in both motion and static pictures,it restrains the effects of line-crawling and fake-shadow brought by the probable bad motion detection effectively and provides better quality.
