旧电影中基于Hough变换直线划痕的检测

Scratch line detection on old movies based on Hough transform

为保护旧电影和国家档案影片,研究了旧电影自动修复与保护的方法。为了有效检测旧电影中常见的直线划痕,分析了直线划痕产生的原因、基本特征、检测方法。在分析Hough原理的基础上,提出了一种基于Hough变换的直线划痕检测方法。实验结果表明,该算法能有效地检测旧电影中的直线划痕,并可为旧电影中直线划痕的自动修复提供理论依据和实现基础。

To protect old movies and national video archives,the method of automatic restoration of old movies and video archives is studied.To effectively detect scratch lines which are common on old movies,its cause of emergence,basic features and detection methods are analyzed.After analyzing the basic principle of Hough transform,a new algorithm of scratch line detection based on Hough transform is proposed.It indicates that the algorithm can effectively detect the scratch lines on old movies,and also provide theoretical basis for inpainting automatic and realization foundation.
