The invention relates to identification means for localising a physically delimited part of the body, which do not involve a long computing time, but nevertheless provide a sufficiently precise identification. The invention also relates to a method for detecting physically delimited parts of the body (face, hand, leg) of a subject depicted in an image, whereby on said image (5) a part of the body (2) is depicted against a background (3). The edge lines (5d, 5e) of the image are only evaluated according to the line direction (5a', 4a', 4b', 5c'), in order to determine by comparison with a model (30), whether the part of the body depicted corresponds to a body-part type predetermined by the model. Line directions (5d', 5e') inside the depicted part of the body and edge line directions (5a) of the depicted and physically delimited part of the body are used for said comparison, which allows their position to be localised and the corresponding positional information to be stored. |
