视频解码自适应亮色分离及其LabVIEW实现

A self-adaptive Y-C separation in the video decoder and its LabVIEW implementation

亮色分离是视频解码中的一个关键技术。文中对此提出了四种适应于不同情况下NTSC制数字复合视频信号解码的亮色分离滤波器,并由此设计了一种基于此四种滤波器的自适应Y-C分离算法。最后通过LabVIEW来实现该算法,论证了算法的可行性。

Y-C separation is a key technology of the video decoder. This paper puts forward four kinds of filter for the Y-C separation of NTSC digital composite video signal in different situations and a self- adaptive Y-C separation algorithm based on the four separation filters. Finally, the self-adaptive algorithm is implemented by LabVIEW and the result demonstrates the feasibility of the algorithm.
