A physically demarcated body part is recognized and located using only a relatively small amount of computation, but with a sufficient degree of recognition accuracy. For this purpose a procedure is proposed for detecting physically demarcated body parts (face, hand, leg) of a person's image (5) if a body part (2) as depicted in front of a background (3). Borderlines (5d, 5e) in the image are only evaluated along line directions (5a′, 4a′, 4b′, 5c′) to determine, by comparing with model (30), whether the body part image corresponds to a type of body part given by the model. In addition, line directions (5d′, 5e′) inside a body part image and borderline directions (5a) of a physically demarcated body part are used to locate and store its position. |
