Förfarande för att bestämma kantpositionen i färgbilde, specielt för färg- och intensitetsövergångar

摘要

A method for determining the edge position in color images, particularly for color transitions and intensity transitions is disclosed. In accordance with the method, the edge locations found in the total image or in individual color extracts coincide as closely as possible. Further, every color value F is changed to a vector representation {overscore (OF)} proceeding from a selected point O of the color space F to determine the edge location K, and in that the transition from a color FL at the left of edge K to a color FR at the right of edge K is determined in order to determine the edge position along a given sampling direction by means of a method based on the vector representation {overscore (OF)}. The method according to the invention is directed for determining the edge position in color images, particularly with detection of color transitions and intensity transitions in color space F.
