Figure 10From: A fast and robust hepatocyte quantification algorithm including vein processingThresholding result with vein. Results for Otsu thresholding (left) and EM (right) methods for the image in Figure 9 without vein exclusion. Otsu thresholding misclassifies the cells, which cannot be restored. EM assigns both cells (darkest spots) and vein (brightest spots) to the same Gaussian distribution. After connected component processing, it is possible to extract the cells from the EM result. However, a number of false positives (in the vein area) is also detected.Back to article page
