摘要
A method identifies and models the distortion in a document using atwo-dimensional nonlinear filter. The two-dimensional nonlinear filter is then usedto improve the performance of optical character recognition systems in recognizingcharacters in documents that have been degraded, as for example by repeatedphotocopy reproductions or by fax transmission.
