Abstract The handwritten numeral string extraction in form document is studied. A method is proposed to effectively discern and capture the characters from overlapping borders based on hybrid binarization. Two key problems are investigated in detail including the location and the extraction on the cell of interest (COI) with broken strokes mended. The extracted handwritten characters remain integrated even for characters in different writing styles. Experimental results demonstrate that the proposed method is efficient.
