A thresholding method is based on edge analysis combined with projection technique. With improved detection of grey level and texture of character objects, the new method offers greater robustness and higher processing speed compared with convensional methods. A detection method is also proposed based on Hough transform for detecting character orientation and making correction. Side experiment results showed the new methods improved successful recognition rate greatly.
