colour of the mass part is quite similar to the colour of the rest of the mammogram. So, if the mass area is larger, fewer clusters will be required while in the mass area is smaller more clusters will be needed. It means the number of clusters required for the mass detection from the mammogram image is inversely proportional to the mass area[3,7,11]. The following shows the results for the fourth clusters of all the images and their respective histograms also obtained using the MATLAB R2013a imhist tool. This can be observed that the affected regions are more accurately located i.e. the identification of affected areas with malignant effects gets more prominent. Figure 12: The processed image of sample 1 and its histogram From figure 12, The tumor was seen when the fourth cluster was applied as compared to the 3 rd cluster. From figure 13, no tumor was seen in the breast as compared to the original image.
