Recognition Algorithm for Falsified License Plate Based on Near Infrared Image Matching-segmentation

Due to complicated irregularity phenomenon of falsified license plate,a recognition algorithm for falsified license plate based on near infrared imaging is introduced.Firstly,the principle and characteristic of falsification which interferes performance of license plate recognition(LPR) are presented.Then an image matching-segmentation-based algorithm is devised on the basis of feasibility analysis to recognize the falsified license plate.Experiment results show that falsified license plate recognition can be implemented by the proposed algorithm,which has higher veracity and more valuable than the other.
