| Abstract: | In this paper, a model for automatic detection of line scratches on digital images is proposed. It consists in a generalization of the Kokaram's model using width and height features of the line profile along with Weber's law, to test scratches visibility on the image. Experimental results show that the algorithm works better than the existing models in detecting true scratches with a lower computing time. |
