Abstract From the Canadian patent

Abstract, Image-pattern-specific separation values are calculated in each case per column for a separation image (PTR) of standardized width (bstd), with the aid of a separation classifier, and the column having the maximum separation value is defined as the right-hand separation column (tr). On the basis of the separation column (tr) 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 …
