| Popis: | 83 An approach to recognition of the handprinted Chinese mail addresses on envelopes, which focuses on processing addresses on standard-size envelopes. There are mainly five stages in the proposed approach, namely pre- processing, location of address blocks, character segmentation, address recognition, and postprocessing. First, a preprocessing stage is designed to filter out noise and to remove unwanted components. Next, a stage of address block location, is used to group the rest components into blocks. Some features are extracted from the blocks to identify the envelope format. And the destination address block is located. The address block is then fed to character segmentation stage to merge the components into characters. Then, in the address recognition stage, the characters are recognized using statistical character recognition algorithm. Since there are errors in the recognized characters, the correct destination address may not be found in this stage. So, the postprocessing stage to modify the erroneous address characters into correct ones according to the contextual relationship among the characters. The proposed approach has been tested on some real envelopes and the experimental results show its feasibility. |
