Abstract
A character recognition system for recognizing a character associated with a query character. The query character has a query character image defined by a query character image array having a pattern of array elements defining on pixels and off pixels for said query character image, in response to training character images also represented by patterns of on and off pixels. The system generates, for each image array, a distance array having a pattern of array elements each identifying a distance value to pixels of selected conditions, thereby identifying distances to artifacts in the respective images. In addition, the system generates distance scores for both the query character and the training character, using the distance arrays, representing the consolidated deviation between the query character image and the training character images. The system includes a massively-parallel processor including a plurality of processing elements to process the training character image arrays in parallel.
