1. Procedure for recognizing types of physically demarcated body parts ( 2 ) like faces, hands, and legs of a person ( 1 ) portrayed in a target image ( 5 ) when at least one, not yet recognized, body part ( 2 ) appears in the target image in front of a background ( 3 ) and its position is indicated by means of positional information obtained and stored appropriately; characterized by (a) the target image ( 5 ) being converted into at least one intermediate image ( FIGS. 2 b and 2 c ) on which edge lines ( 5 a , 5 b , and 5 c ) are accentuated, to be evaluated in a following step in regard to their direction ( FIG. 2 e , 4 ); (b) preparing a model ( FIG. 8, 30 ) based on other edge line information obtained previously. The directions of the edge lines in the model are retained for determining which other model or which other edge line information corresponds to the sought-for type of body part ( 2 ); where only edge line directions of a body part image are evaluated in comparison with the model ( 30 ) to determine whether the body part image ( 2 ) appearing in front of the background ( 3 ) corresponds to the sought-for body part and whether the accompanying positional information should be determined and stored;
