摘要
互补高、低通滤波方案是兼容发展高清晰度电视诸多方案的一种.在互补高、低通滤波方案中滤波器制作的好坏直接关系到恢复图像的质量.本文着重介绍互补高、低通滤波方案中二维高、低通滤波器的设计方法及设计结果.模拟实验证明:二维高、低通滤波器应用在互补滤波方案中,图像质量得到很好恢复.
The complementary high-pass and low-pass filtering television system (CFTV) is one of the projects in developing HDTV. The quality of filters in the CFTV system directly affects that of the restored picture. This paper is mainly centred on the designing method of the two-dimensional high-pass and low-pass digital filters in the CFTV system and its resultant data both in the still area and the motion area. It is shown by simulation that filters designed in this way are applicable to the CFTV system with high restored picture quality.
