摘　　要：分析三点中间滤波和沿自适应滤波两种去隔行算法各自特点,将两者相结合,提出了一种新的自适应去隔行算法。该算法通过检测图像运动信息,对动态和静态图像分别采用不同的滤波方法:动态图像用沿自适应滤波,静态图像用三点中间滤波。算法在处理动态和静态视频信号时,都能达到较好的效果。由于对动态信息的检测精度不敏感,该算法比较稳定,并且能节省硬件资源。此算法用CPLD作为主控芯片得以实现。A new motion adaptive de-interlacing method by combining three-point median filter and edge directional line averaging filter have been developed. Three-point median filter is used for deal with static pictures and edge directional line averaging filter is used for deal with moving pictures. This method works well in both static pictures and moving pictures. This method has been implemented with CPLD.
