Abstract:According to the analysis of the threshold method for image segmentation based on the traditional 2D gray-level histogram which partitioned the areas with some wrong pixels and processes slowly,this paper brought forword a new method which built the 2D histogram using the difference of the gray-level in the neighborhood.Implemented 2D Otsu method based on between-cluster variance.This method well considered the departure of the gray-level and the information of area gray-level. The experiment shows that the segmentation result of this method is better especial in biological image segmentation and its computation time is reduced much which can apply in the real-time segmentation.......
