基于分水岭算法的重叠细胞分割

基于分水岭算法的重叠细胞分割 %% 1.Make a binary image containing two overlapping circular objects. %% 2.Compute the distance transform of the complement of the binary image. %% 3.Complement the distance transform, and force pixels that don't belong %% 4.Compute the watershed transform and display the resulting label matrix as an RGB images.
