摘要
本文分析了视频预处理的De-interlace算法。在分析了线性滤波De-interlace算法缺点的基础上,提出了像素相关性判断改进方法,改善了处理的效果。针对主要是水平或者垂直方向运动的视频,运动补偿法的块匹配算法存在速度慢的缺点,提出了行搜索运动补偿De-interlace算法,改善了预处理效果,提高了预处理速度。最后,对这些算法进行了评估与比较。
This paper analyzes de-interlace techniques. Based on analyzing the disadvantage default of linear filtering de-interlace techniques, an estimating sample correlation method is proposed, which improves the de-interlacing performance. For motion compensation algorithm has the low speed of working, this paper proposes the method of line-researching algorithm based on MC de-interlacing for horizontal or upright moving video signal, it is concluded that it can improve the de-interlacing performance and speed. These methods are finally evaluated and compared.
