Combining with the characters of celluloid films,this paper provides a digital restoration system based on celluloid films.The restoration methods of blotches improve the ratio between correct detection results and false alarms by employing texture matching.Intensity flicker correction based on motion compensation and threshold method is developed,which improves the efficiency of the method and reduce the false alarms.Scratch lines detection method based on canny theory and spa-temporal is proposed,which enhances the correct detection rate by obtain the length,start point and end point of scratch line accurately.
