Abstract
In order to overcome the shortcomings of large volume,high cost ,low recognition accuracy and poor adaptability in PC seal identification system ,an embedded seal imprint identification system based on SIFT-SVM was designed .The system first computed the SIFT characteristics of the seal im-age and further constructed feature vector based on SIFT matching .The seal feature vector was used to train support vector machine .The SVM's penalty factor and kernel parameter were optimized by genetic algorithm to get the best recognition performance .The system used the ARM11 processor as the core unit of the feature extraction and recognition and used the ZC301 camera to acquire image . The buzzer ,LED and LCD were used as alarm display devices .The experimental results show that the system achieves a good recognition rate of 93 .5% in the cases of seal blur ,rotation and so on .It still has good applicability when seal's stroke is only in 5% thickening .The system has the advantages of good recognition accuracy ,strong applicability ,small volume and flexible design .关键词
