Abstract
In a system and method for automatically segmenting a scanned document to separate areas containing different types of information such as black/white text or graphics, continuous tone pictures, and half-tone pictures, the document is divided into a number of subimages and the individual subimages are classified in an initial labeling phase. The initial label matrix thus obtained is relaxed in a subsequent step so that a pattern of uniformly labeled segments corresponding to the areas in the document containing different types of information is the result. In order to speed-up the system and/or improve the robustness thereof, the number of initial labels used in the initial labeling step is selected larger than the number of types of information to be distinguished. The number of initial labels is then reduced in the relaxation step on the basis of a series of context rules.
