| Abstract: | 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. |
