This paper presents an enhanced dental identification method based on both the contours of teeth and dental works. To reduce the alignment error caused from unreliable contours, we propose a point-reliability measuring method and weigh each point based on its reliability when calculating the Hausdorff distance (HD) between the contours. For reducing the alignment error caused from incomplete tooth...
Accurate grading for hepatocellular carcinoma (HCC) biopsy images is important to prognosis and treatment planning. In this paper, we propose an automatic system for grading HCC biopsy images. In preprocessing, we use a dual morphological grayscale reconstruction method to remove noise and accentuate nuclear shapes. A marker-controlled watershed transform is applied to obtain the initial contours...
