a- Write an algorithm for segmenting a color image into two regions using C-means clustering. Explain how the decision is taken for classifying each color pixel. b- Assume that the PDFs of intensities inside and outside an object are given by:- p(x/01) = N(100, 1500) and p(x/w2) = N(50, 1000) respectively. In this x , problem x is the gray scale value varying from 0 to 255. = I. Find the optimal threshold for segmentation. Find the probability of error that corresponds to the optimal threshold
