Abstract
A method for thresholding a gray scale matrix representative of an image to generate binary matrix representative of the image. Elemental features of the image are determined and characterized, and a plurality of thresholding algorithms is selected. For each algorithm a sequence of binary matrices is generated as scaling factor applied to the algorithm is varied. Features of each binary matrix are determined and characterized and compared to elemental features of the image. For each determined feature which matches a an elemental feature of the image a score is incremented; and for each determined feature which does not match the score is decremented. The binary matrix having the highest score is selected.
