Wavelet based intelligent techniques for automatic identification of motor vehicles: a comparative study

The vehicles of neighbouring states are more prone to violate Indian Motor Vehicles Act, 1988. An algorithm has been developed to automatically recognize the vehicles not registered in Jharkhand, a state of India for appropriate legal action using wavelet based intelligent techniques. The image of Vehicle Licence Plate (VLP) is extracted using Extended Hough Transform (EHT). Four features are obtained using four levels of decomposition using Haar wavelet and used as inputs to different classifiers. A comparative assessment regarding the efficacy of all classifiers indicates SVM to be the most suitable classifier for the intended automated VLP identification.
