METHOD AND APPARATUS FOR DETECTING OBJECTS

A method for detecting an object on an image representable by picture elements includes: "determining first and second adaptive thresholds for picture elements of the image, depending on an average intensity in a region around the respective picture element", "determining partial obje...

Beschreibung
Zusammenfassung:	A method for detecting an object on an image representable by picture elements includes: "determining first and second adaptive thresholds for picture elements of the image, depending on an average intensity in a region around the respective picture element", "determining partial objects of picture elements of a first type that are obtained based on a comparison with the first adaptive threshold", "determining picture elements of a second type that are obtained based on a comparison with the second adaptive threshold" and "combining a first and a second one of the partial objects to an extended partial object by picture elements of the second type, when a minimum distance exists between the first and the second of the partial objects, wherein the object to be detected can be described by a sum of the partial objects of picture elements of the first type and/or the obtained extended partial objects".
