ABSTRACT:
For performing optical character recognition and other scanned document image processing the method for unshading dot shaded areas performs a statistical dot size analysis to determine the distribution of the dot sizes in the dot shaded area. In a separate step the most suitable dot size limitation is determined, followed by deleting dots falling within the so determined dot size limitation.
