Abstract

Segmentation of touching characters in mathematical formulas needs a different method from the one for text lines, because these characters may occur in horizontal, vertical or diagonal directions. Our segmentation method is based on the projection profiles of a given binary image and minimal points of the blurred image obtained by applying the Gaussian kernel to the original image.
