Abstract:
1. A method for post optical character recognition font size determination, comprising: with a processor, aggregating optical character recognition output from an associated optical character recognition engine into a plurality of character strings, the optical character recognition output comprising character code information and bounding box information; collecting measurements from each of the plurality of character strings, the measurements corresponding to a number of observations of heights associated with each character in each character string, wherein the heights correspond to an alignment of the bounding box of each character in each character string with an ascender-line, a cap-line, a digit-line, a mean-line, a base-line, or a descender-line; generating at least one histogram for each character string in accordance with collected measurements for each of the ascender-line, the cap-line, the digit-line, the mean-line, the base-line, and the descender-line; selecting a pivot height in accordance with the at least one generated histogram for each of the plurality of character strings, the pivot height corresponding to a height of the ascender-line, the cap-line, the digit-line, the mean-line, the base-line, or the descender-line; determining a height for each character string of the plurality thereof in accordance with the selected pivot height; for each of the plurality of character strings, normalizing the determined height by a preselected factor associated with the selected pivot height; and determining a font size for the optical character recognition output based in accordance with the normalized height.
