Abstract
A method of recognizing a character including the steps of reading sample characters and generating an image corresponding to the sample characters. Then calculating density projections of each sample characters. A primitive characteristic vector is then extracted from each density projection. Compression then occurs so that an optimal distinction vector and a corresponding characteristic space can be determined. A character to be recognized is then read and an image corresponding to said character to be recognized is generated. A density projection is then made from the image of the character to be recognized. A primitive characteristic vector is then made from the density projection of the character to be recognized. A secondary characteristic vector is then produced by projecting the primitive characteristic vector of the character to be recognized into the compressed characteristic space. Finally one of the sample characters is outputted, based upon the secondary characteristic vector, as the recognized character.
