Zusammenfassung: | The invention aims to provide a film archive patch damage detection method based on a VSF visual saliency map, and the method combines a frame difference method with the visual saliency map, and only needs to calculate the saliency map of a suspicious region processed by the frame difference method. And performing double threshold judgment on the suspicious region to quickly detect whether the frame image has plaque damage or not. According to the method, the algorithm speed can be increased, the detection task of large data volume can be better coped with, and the detection efficiency and accuracy are improved.
本发明的目的在于提供一种基于VSF视觉显著度图的胶片档案斑块破损检测方法,利用帧差法与视觉显著度图相结合的方法,只需计算帧差法处理后可疑区域的显著度图,再对可疑区域进行二重阈值判定便可快速检测出帧图像是否存在斑块破损。此发明能够提高算法速度,可以更好地应对大数据量的检测任务,提高检测效率和准确性。 |
