| Abstract: | In this paper,image segmentation algorithm with double threshold based on both one-dimentional and two-dimentional Otsu method is described.Then, a one-dimentional Otsu multi-threshold segmentation algorithm based on the average grey value of the pixels' neighborhood is proposed,which has the merit of both speed and accuracy.It is applied to the multi-objects automatic segmentation of MRI brain image and gets a better result than one-dimentional Otsu method. |
