Abstract: One approach based on block clustering is proposed to locate the printed character regions and the other approach based on natural language understanding is presented to improve the recognization rate. Meanwhile, each model in the system is briefly analyzed and a complete frame is carried out. Performance evaluation is processed based on 1 589 pages of scanned bankcheck images and the accuracy rate attains 90.54%.
