摘　　要：针对当前应用ELA算法,判断隔行视频图像的边沿信息方向存在的缺点,提出了一种改进型ELA运动自适应边沿插值去隔行算法。利用MATLAB软件进行仿真分析,结果表明,改进型ELA自适应边沿去插值去隔行算法效果良好,改善了应用其他去隔行算法产生的锯齿效应。By judging interlaced video image edge direction information for the shortcomings of the current ELA algo rithm, we propose a improved ELA motion adaptive edge interpolation deinterlacing algorithm. Analyzed by MATLAB soft- ware simulation,the results show that the improved ELA deinterlacing algorithm has good effect interlacing, and improved application sawtooth effect produced by other deinterlacing algorithms.
