Abstract
In character normalization for optical character recognition preprocessing employing horizontal and vertical scaling factors A and B, the value of each pixel in the normalized character image superimposed on the original character image is determined from the values of the pixels in the original image lying within an elliptical neighborhood surrounding the normalized character image pixel and having major and minor elliptical axes proportional to A and B.
