<P>PROBLEM TO BE SOLVED: To provide a method and a device for converting a document to a mixed raster content format having a multiple foreground surface. <P>SOLUTION: A dependent minimum/maximum module is provided, which receives image data and generates a dependent minimum value and a dependent maximum value in a window around an object pixel. A dynamic threshold module generates, for example, continuity data and enhanced data, which are suitable for blob identification, based on the dependent minimum value and the dependent maximum value. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
