Abstract: Image-pattern-specific separation values are calculated in each case per column for a separation image of standardized width, with the aid of a separation classifier, and the column having the maximum separation value is defined as the right-hand separation column. On the basis of the separation column predetermined by the separation classifier, an attempt is made, starting from the upper pixel of the separation column, to find a separation path which, in the absence of a white column, is formed within a separation region, which is located on both sides of the separation column, partially by contour tracing and, if no white path can be found by contour tracing, partially by forced separation along the separation column.
