File Name: a robust and efficient approach to license plate detection .zip
The rapid development of the license plate recognition technology has made great progress for its widespread uses in intelligent transportation system ITS. This paper has proposed a novel license plate detection and character recognition algorithm based on a combined feature extraction model and BPNN Backpropagation Neural Network which is adaptable in weak illumination and complicated backgrounds. Firstly, a preprocessing is first used to strengthen the contrast ratio of original car image. Secondly, the candidate regions of license plate are checked to verify the true plate, and the license plate image is located accurately by the integral projection method. Finally, a new feature extraction model is designed using three sets of features combination, training the feature vectors through BPNN to complete accurate recognition of the license plate characters. The experimental results with different license plate demonstrate effectiveness and efficiency of the proposed algorithm under various complex backgrounds.

A Robust and Efficient Approach to License Plate Detection Abstract: This paper presents a robust and efficient method for license plate detection with the purpose of accurately localizing vehicle license plates from complex scenes in real time. A simple yet effective image downscaling method is first proposed to substantially accelerate license plate localization without sacrificing detection performance compared with that achieved using the original image. Furthermore, a novel line density filter approach is proposed to extract candidate regions, thereby significantly reducing the area to be analyzed for license plate localization.
Due to the complexity in real world, many existing license plate detection and recognition approaches are not robust and efficient enough for practical applications, therefore ALPR still a challenging task both for engineers and researchers. The framework not only accelerates the processing speed, but also achieves a better match between the two tasks. Other contributions includes an anchor-free LP localization network based on corners using a novel MG loss is proposed and a multi-resolution input image strategy is adopted for different tasks to balance the operation speed and accuracy. Experimental results on CCPD data set show the effectiveness and efficiency of our proposed approach. The resulting best model can achieve a recognition accuracy of Automatic License Plate Recognition ALPR plays an important role in Intelligent Transportation System ITS which is widely used in traffic management, intelligent surveillance and parking management in large cities [ 20 ], hence, attracts considerable research attentions in recent two decades.
It is valuable in numerous applications, such as entrance admission, security, parking control, road traffic control, and speed control. The image is then used to detect vehicles of any type car, van, bus, truck, and bike, etc. Furthermore, this image is processed using segmentation and OCR techniques to get the vehicle registration number in form of characters. Once the required information is extracted from VLNP, this information is sent to the control center for further processing. ANPR is a challenging problem, especially when the number plates have varying sizes, the number of lines, fonts, background diversity, etc. However, only a limited work exists for Pakistan vehicles.
