Abstract

License plate extraction is an important step of License Plate Recognition (LPR) in Intelligent Transportation System. This paper presents a hybrid license plate extraction method which combines edge detection and support vector machine (SVM) filtering. Observing that there are many vertical edges in the license plate region, we firstly extract several candidate license plates according to vertical edge density, after that these candidate license plates are verified by a SVM classifier based on Histograms of Oriented Gradient texture descriptor (T-HOG). Promising results are achieved in the experiments.
