互补滤波提高电视图像清晰度的研究

Research on Increasing Picture Resolution Based on Complementary Filtering

本文在分析了几种不同处理方案的电视三维谱分布的基础上,提出一种利用高、低通互补滤波压缩细节信息的传输带宽,以兼容方式实现较高清晰度电视的方案。

In this paper the three-dimensional spectra of television signals sampled in different patterns are analysed and a compatible system with increased resolution is put forward. In this system the additional detail information is delivered in complementary high-pass and low-pass filtering and the transmitting standard for current systems can be kept unchanged.
