摘要： A system, method and program product for cleaning a black white image. A system is disclosed that includes a filtering system that applies a filter to the black white image, wherein the filter examines a set of neighboring pixels of each black pixel and determines if a black pixel being examined should be converted to a white pixel; and a recursive application system that causes the filtering system to repeatedly re-filter the black white image until a determination is made that the black white image is sufficiently cleaned.

摘要： A method is disclosed for detecting fraud. The method optically recognizes a character imprinted with a magnetic ink on a medium using a first optical character recognition algorithm. The method also optically recognizes the character using a second optical character recognition algorithm. In addition, the method magnetically recognizes the character using a magnetic recognition algorithm. The method determines if the character is potentially fraudulent based on the recognition results of the scan using the first optical character recognition algorithm, the scan using the second optical character recognition algorithm, and the magnetic scan. If the character is potentially fraudulent, the method communicates a fraud indicator.

A first optical character recognition module optically recognizes a character imprinted with a magnetic ink on a medium using a first optical character recognition algorithm. A second optical character recognition module also optically recognizes the character using a second optical character recognition algorithm.
