Character image enhancement by selective region-growing
نویسندگان
چکیده
Preprocessing of character images is an important step in recognition. We describe a method of enhancing binary character images to assist the subsequent recognition process in both handwritten and machine-printed documents. The method performs selective and adaptive stroke "filling" with a neighborhood operator which emphasizes stroke connectivity. An improvement of 7% points was realized in recognition of address fields.
