Abstract
This paper presents features for measuring the congestive extent as a means for diagnosing internal hemorrhoids using endoscopic images. A computer-aided diagnosis for the hemorrhoids could be effective for young or even general practitioners as a second opinion because diagnosis of hemorrhoids needs much experience. Considering characteristics of the hemorrhoids, the proposed method measures degree of the congestion in the images and the size of the congestive regions as abnormalities of the hemorrhoids. Experimental results of the discrimination between normal and abnormal cases using the proposed abnormalities for 204 images (96 normal cases and 108 abnormal cases) have shown that the abnormalities are well effective to measure degree of the congestion in internal hemorrhoids.
