| Abstract: | In this paper, the segmentation is performed on images, which are obtained by the addition of stochastic noise, maximum a posterior (MAP) estimate method, fuzzy C-means method and thresholding
method of Otsu. The analysis with contrast is done on their output, and the curves of changing
segmentation error with standard variance are drawn. Then the same process is carried out on the noisy
images which are filtered with different methods. |
