Figure 11From: A fast and robust hepatocyte quantification algorithm including vein processingThresholding result: Histogram. Results for Otsu thresholding and EM methods overlaid with image histogram for Figure 9 before (left) and after (right) vein exclusion. When the vein is not excluded (left), Otsu thresholding misses the cell class. With vein exclusion (right), Otsu thresholding is still not able to separate the cell class, as the variations inside the background class are more noticeable. EM assigns in both cases (left and right) all non-representative classes (cells and vein) to the same Gaussian curve.Back to article page
