Claim One:
1. A method for ulcer detection, the method comprising: obtaining an image comprising image pixels; calculating ulcer head scores for image pixels, each score correlated to the probability that the color of the associated image pixel is typical to ulcer heads; calculating ulcer red region scores for image pixels, each score correlated to the probability that the color of the associated image pixel is typical to ulcer heads, or to ulcer red regions, or to a region that is neither ulcer head nor ulcer red region; comparing the ulcer head scores to an ulcer head threshold level and, based on the comparison results, obtaining potential ulcer head candidates; comparing the ulcer red region scores to an ulcer red region threshold level and, based on the comparison results, obtaining potential ulcer red region candidates; forming ulcer candidates by creating pairs, each pair including a potential ulcer head candidate and a potential ulcer red region candidate; determining a grade for each ulcer candidate, the grade indicating the probability that the ulcer candidate is an ulcer; and determining a score for the image based on the grades, the score indicating the probability that the image includes an ulcer.
