Abstract
A method, system and computer program product for recognizing cursive and non-cursive handwriting. The invention comprises capturing a handwritten character as an image of pixels, partition the image into a plurality of segments each having a pixel ratio of the number of pixels in the segment divided by the total number of pixels in the image, and compare the pixel ratio for each segment to a value range associated with a corresponding segment of a reference character. The handwritten character is recognized as the reference character if more than a predetermined number of the segments in the image have the pixel ratios within the respective value ranges of the reference character.
