Bildverarbeitungsverfahren zur örtlichen Bestimmung des Zentrums und der Objekte, die sich gegen einen Hintergrund abheben, und Vorrichtung zur Durchführung des Verfahrens

摘要

The method involves using an image with an essentially uniform pattern of pixels on an essentially uniform contrasting background. The image is scanned along a line (delta) of the image starting at an initial pixel (y1). For each pixel (Pi) of order yi a primary function ÄE(a,yi),V(a,yi)Ü is calculated as accumulated sums in memory calculated at intervals along the line. A secondary function is derived allowing the calculation and display of the centre line of the image and its half width at key locations.
