License plate detection system in rainy days
Proceedings 2003 IEEE International Symposium on Computational Intelligence in Robotics and Automation. Computational Intelligence in Robotics and Automation for the New Millennium (Cat. No.03EX694), 2003License plate recognition is very important in an automobile society. However, it is very difficult to do it, because a background and a body color of cars are similar to that of the license plate. Furthermore, the detection of cars in a moving at a very high-speed is difficult to be done. In this paper, we propose a new robust thresholds determination

Multiple License Plate Detection for Complex Background
19th International Conference on Advanced Information Networking and Applications (AINA'05) Volume 1 (AINA papers), 2005This paper presents a wavelet transform based method for extracting license plates from cluttered images. The proposed system consists of three major stages. First, a wavelet transform based method is used for extracting important contrast features as guides to search for desired license plates.

A comparison study on motorcycle license plate detection
2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2015License plate detection and recognition are mostly studied on automobiles but only few on motorcycles. As motorcycles are becoming popular for local transportation and environmental friendliness, the demands for license plate recognition have been increasing in recent years.

License Plate Detection Using Neural Networks
2009This work presents a new method for license plate detection using neural networks in gray scale images. The method proposes a multiple classification strategy based on a Multilayer Perceptron. It consists of many classifications of one image using several shifted window grids.

Fuzzified Gabor filter for license plate detection
Engineering Applications of Artificial Intelligence, 2016This paper presents a new algorithm for detecting and extracting license plates from a complex image by using a fuzzy two-dimensional Gabor filter. The filter parameters are fuzzified to optimize the Gabor filter. In particular, the orientation and wavelengths of the Gabor filter are fuzzified.

License Plate Detection and Recognition in Unconstrained Scenarios
2018Despite the large number of both commercial and academic methods for Automatic License Plate Recognition (ALPR), most existing approaches are focused on a specific license plate (LP) region (e.g. European, US, Brazilian, Taiwanese, etc.), and frequently explore datasets containing approximately frontal images.

An algorithm for skew license plate detection
Proceeding of the 11th World Congress on Intelligent Control and Automation, 2014An efficient skew detection algorithm is proposed based on geometric constraint of license plate image. The highest of image outline would be treated as fundamental information to calculate the skew angle. Experimental results demonstrate that the algorithm proposed here has higher precision, faster speed and less computation.

Research on License Plate Detection Based on Wavelet
2008License Plate Recognition (LPR) is one of the critical techniques for ITS. It can be widely used in traffic control and traffic surveillance. License Plate Detection is one of the important components in LPR. In this paper, we propose a method based on wavelet transform to locate the plate zoom.
