LPR (License Plate Recognition) is a foundation component of modern transportation management systems. It uses a set of computer image-processing technologies to identify vehicle by its license plate. Character recognition is the core of LPR, which is essentially a multi-classification problem. The challenge is how to recognize every character of the license plate accurately and rapidly in case of...
In this paper, a novel method of the number license plate location based on top-hat transform and wavelet transform is proposed. First, top-hat transform is used to suppress the background of image and remove the nonuniform illumination. Second, vertical edge detection and morphology filter is applied to the image, coarsely location of the license plate is completed by the structural characteristics...
Detecting vehicles from video sequence is very challenging due to the wide varieties of vehicle appearances and the complexity of the backgrounds. At present, many algorithms in the image recognition have a narrow applicability and a weak real-time. Aiming at this problem, a recognition method which was combined by features extraction using Gabor wavelet and BP neural network algorithm for the classification...
