Suppose that an image has the following intensity distributions, where pi(z) corresponds to the intensity of objects and p2(2) coresponds to the intensity of the background. Assuming that P1 and P2 ind the optimal threshold between object and background pixels. P2 (z) PI (z) 3 Note P1, and P2 are a priori probabilities, Suppose that an image has the following intensity distributions, where pi(z) corresponds to the intensity of objects and p2(2) coresponds to the intensity of the background.
