Abstract

Die Erfindung betrifft eine Bildverarbeitungsvorrichtung, mit der eine Bilderkennung in Echtzeit erfolgen kann und die mit nur sehr wenig oder sogar keinerlei a-priori-Information in der Lage ist, eine zutreffende und zuverlässige Erkennung von Objekten durchzuführen. Dazu werden mittels eines Rechenwerks die Verbindungswahrscheinlichkeiten zwischen jeweils zwei Konturpunkten unter Berücksichtigung des Abstands der Punkte zueinander ermittelt. Weiterhin ist zumindest ein Klassifikator vorgesehen, welcher aus Mengen von berechneten Verbindungswahrscheinlichkeiten Teilmengen mit zumindest drei Verbindungswahrscheinlichkeiten für mögliche Verbindungen zwischen zumindest drei benachbarten Konturpunkten, wovon einer ein zuvor bestimmter zentraler Konturpunkt ist, auswählt und für jede Teilmenge denjenigen zum zentralen Konturpunkt benachbarten Konturpunkt aussortiert, der eine mögliche Verbindung mit der geringsten Verbindungswahrscheinlichkeit zu einem benachbarten Konturpunkt aufweist, sofern die Verbindung nicht zwei zum Zentralpunkt benachbarte Punkte verbindet und im Anschluss daran in eine Konturpunktliste die nicht aussortierten Konturpunkte mit Konnektoren einträgt, welche die verbleibenden Verbindungen zum Zentralpunkt kennzeichnen.
