Hematoxylin and eosin-stained sections representing ten cases of hepatocellular carcinoma showed many tumor cells with ground-glass cytoplasm identical to that found in hepatocytes containing hepatitis B surface antigen (HBsAg). However, the aldehyde fuchsin stain was negative, as were the were the immunoperoxisidase stains for HBsAg and core antigen (HBcAg). Electron microscopically, the groun...

In this work we present an automatic algorithm for detection of mycobacterium tuberculosis from stained sputum smear images applying a novel method of tubeness filtering in conjunction with Otsu thresholding and connected component analysis. This eliminates human effort and measurement error from the detection of the bacteria, which normally requires a lab technician or pathologist to load a gl...
