摘要:
This invention concerns recognizing and locating a physically demarcated body part by using only a relatively small amount of computation, but still produces 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) is 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.

摘要:
A method for altering the recording setting of an image recorder for the recording of an object is disclosed. A setting influencing at least the recording of the object, such as aperture, illumination time or focussing (30,40,50), is controlled using at least one object section (1a; 1b) in the object image (60). The object section is selected by means of a previously determined/fixed object type (9). The determined type is localized in the object image (1) by means of an image analysis (10) to give localisation information (PD). The object section (20) is determined from the localisation information to influence the setting of the image recorder from the at least one fixed object section (1a,1b).
摘要:
In a method for characterizing a signal, which represents an audio content, a measure for a tonality of the signal is determined, whereupon a statement is made about the audio content of the signal based on the measure for the tonality of the signal. The measure for the tonality of the signal for the content analysis is robust against a signal distortion, such as by MP3 encoding, and has a high correlation to the content of the examined signal.
