Thai Character Recognition Using “Snakecut” Technique
Optical character recognition has become one of the powerful tools in the area of pattern recognition and artificial intelligence. Our research targets practically to Thai character recognition on Thai national identification cards. We propose a Thai character recognition technique, so called “Snakecut”. It is invented by iterative investigations of the Thai characters. The “Snakecut”, an unsupervised technique, is able to trace around each character, meticulously. A set of 26 weighted parameters are employed to further tuning recognition performances. Experiment results accuracy rates are 83.10% for pure Thai characters and 92.96% for a mixture of numbers and Thai characters with some limitations.
