Abstract

Abstract Translated from German Bei der Anordnung zur Verschiebungsvektorsuche in der digitalen Bildanalyse wird in einem Array-Rechenwerk (1) die Summe der Betragsdifferenzen von Bildpunktdaten zweier Bilder für mehr als ein Bildpunktpaar parallel berechnet und diese Summen in einem nachgeschalteten Akkumulator-Rechenwerk (2) aufaddiert. In einem dem Akkumulator-Rechenwerk nachgeschalteten Kontroll-Rechenwerk (3) wird durch Ermittlung des Minimums einer Anzahl derart aufaddierter Werte als Bewegungsvektor der Verschiebungsvektor ermittelt. In the arrangement for displacement vector search in digital image analysis, the sum of the difference in magnitude of pixel data of two images for more than one pair of pixels is calculated in parallel in an array arithmetic unit (1) and these sums are added up in a downstream accumulator arithmetic unit (2). In a control arithmetic unit (3) connected downstream of the accumulator arithmetic unit, the displacement vector is determined as the motion vector by determining the minimum of a number of values added up in this way.
