摘要
去隔行算法是电视扫描格式转换和数字视频处理的一项关键技术.本文分析了现有的各种去隔行算法,在此基础上,采用了一种运动自适应去隔行算法.该算法通过运动检测将图像中的像素进行分类,针对不同类型的像素点自适应的采取不同的插值算法,提高了图像的质量.同时与基于块匹配的运动补偿去隔行算法相比,易于硬件实现.
The de-interlacing algorithm is an key technique in the fields of digital video processing and conversion of video scan formats. This article discusses some existed algorithms of deinterlacing , and then presents a motion-adaptive deinterlacing method. This algorithm categorizes the pels of an image through motion detection, and adopts a different algorithm according to the type of pels. The algorithm improves the image quality. It can be easily implemented by hardware compared with the deinterlacing method based on the block matching.
