Abstract :
We propose a new method for the recognition of unconstrained handwritten words consisting of Korean and numeric characters. To overcome the difficulty of separating touching characters, we adopt an over-segmentation technique and we find the optimal segment combination using a lexicon-driven word scoring technique and a nearest neighbor classifier. The optimal combination gives the final segmentation positions for individual characters with the best matching word in the lexicon. The proposed system has yielded an accuracy of 90.64% for 908 word images on live mail pieces
