摘要：In this paper a color descriptor designed for bleeding detection in endoscopic images is proposed. Thedevelopment of the algorithm was carried out on a representative training set of 36 images of bleeding and 25 clearimages. Another 38 bleeding and 26 normal images were used in the final stage as a test set. All of the consideredimages were extracted from separate endoscopic examinations. The experiments include color distribution analysis inRGB and HSV color spaces, measured over the training set. Next, the color descriptor based on the statistics of pixelvalues is introduced. The main idea behind the algorithm is to measure the ratios of bleeding and non-bleeding casesfor each pixel color value appearing in the training set. Two variants of the descriptor are proposed, first dedicatedfor exact blood color detection, and second, more lenient, for identifying colors close to bleeding. The experimentalevaluation lead to satisfactory results, surpassing the values anticipated basing on the theoretical considerations thatwere conducted earlier.
