Abstract
A method and system are disclosed for post optical character recognition font size determination. Optical character recognition output from an optical character recognition engine that includes character and bounding box information is aggregated into character strings. Measurements are then collected from each character in each character string that correspond to alignment heights of the top or bottom of the character with an ascender-line, a cap-line, a digit-line, a mean-line, a base-line, or a descender-line. Histograms are formed for each of these heights for each character string from the collected measurements. Based on the histograms, a pivot height is selected and used to determine the relative font size of the character string. The relative font size is normalized using a preselected factor associated with the selected pivot height. The normalized font size is then output as the font size of characters in the optical character recognition output.
