【Abstract】 Seal imprint verification has an important value in the implementation of digital signature in banks for saving and exchanging in the whole city. This paper researches this question from the view of pattern recognition and image processing and proposes new methods in feature extraction and classifier. The differences of image based statistical feature extraction method and the skeleton image based structural feature extraction technique are developed. Two kinds of effective feature, i.e., the key point distance feature and the stroke curvature feature, are suggested. Based on the above features, a support vector machine (SVM) based multi feature and multi classifier fusion is proposed. Experimental results indicate that the proposed methods can significantly improve the recognition accuracy and reliability compared to the previous seal imprint automatic verification approach.更多还原
