Thresholding result without vein. Results of Otsu thresholding (left) and EM (right) methods for the image in Figure 9 after vein exclusion. Otsu thresholding splits the background into two classes instead of separating cell and background classes, as the cell class is negligible. EM assigns all non-representative classes (cells and vein) to one Gaussian curve such that, after vein exclusion, the cell class is correctly extracted.
