【Abstract】 Otsu is one of the widest application algorithms of image segmentation for automatic selecting threshold.On the basis of this method,an improved algorithm for the selection of image threshold is given in according to introduce the gray level and gradient papping(GGM).The results show that this new algorithm can detect the object and restrain the noise effectively and has a widespread prospect.更多还原
