The incomplete characters recognition in the license plate, characters can be divided into linear character and curve character. For the curve characters, used a method of statistic the number of character holes as the character characteristics for feature extraction, which extended seed filling algorithm in the Computer Graphics .For linear characters, we proposed a method of extracting a character conversion slope of the line feature by Hough transform, which had a good effect on linear character recognition.
