摘要：Authors review the existing bleed ing detection methods focu sing their attention on the image processing techniques utilised in the algorithms. In the article, 18 methods were analysed and their functio nal co mponents were identified. The authors proposed six different groups, to which algorithms' components were assigned: colour techniques, reflecting features of pixels as individual values, texture techniques, considering spatial dependencies between pixels, contour techniques for edges and contours, segmentation techniques for dividing images into meaningful regions, decision mechanisms for final interpretation of the image and other techniques that do not match any of the introduced groups. Authors conclude that the al gorithms could be still improved by applying more co mplete sets of techniques to address the importance of visual features of endoscopic bleeding. Also, improvement is possible in the area of decisive classifiers
