一种基于嵌入式系统的快速去隔行算法

An embedded-system based fast deinterlacing method

文章针对嵌入式平台实时性要求高的特点,提出一种基于运动自适应的快速去隔行算法。运动检测部分采用改进的4场检测方法,检测结果更加平滑。对于检测为静止的像素采用场复制插值法,保留图像细节,对于运动像素则采用分级边沿平均插值法,克服了传统的边沿平均插值法固有的缺点。

To satisfy the real-time requirement of the embedded system,an adaptive motion based fast deinterlacing algorithm is proposed in this paper.The improved four-field motion detection method is adopted to get more smoothing detection results.In the detected static area,field duplication is used to keep more image details,while in the detected motional area,ranked edge-based line average（RELA） method is used to overcome the intrinsic defect of traditional edge-based line average（ELA） method.
