This paper proposes an algorithm that automatically reads license plate from videos that has taken from personal devices. Unlike commonly used license plate reader in toll payment or road control system, video from personal devices usually has more variation in viewing angle, resolution, shutter speed and so on. This work read single frame from video first, then extract the license plate by det...

Vehicle License Plate Detection (LPD) is an important step for the vehicle plate recognition which can be used in the intelligent transport systems. Many methods have been proposed for the detection of license plates based on: Mathematical morphology, Discrete Wavelet Transform, Hough Transform and others. In general, an LPR system includes four main parts: Vehicle image acquisition, license pl...

This project will focus on the design of algorithms used for extracting the license plate from a single image, isolating the characters of the plate and identifying the plate region. This section presents a method for extracting license plates based on the Hough t rans form . The algorithms were developed using a set o f t r a i n i n g i m a g e s , a n d t e s t e d o n images taken under var...

This paper proposes to use the method of edge detection, morphology, and dynamic image thickening for license plate extraction from images. In the proposed algorithm, a different thickening is used for rear and front parts of the image; besides, to increase the segmentation rate, determination of the license plate frame using standard deviation in the vertical histogram diagram is suggested. Fu...

Car license plate detection has been always a challenging task in the context of traffic control and traffic offenses. In this paper, the problem of license plate detection from gray scale images taken in natural conditions is addressed. Our car plate database consists of images with severe imaging conditions such as low quality images, far distanced cameras, and severe weather conditions. The ...

License plate detection (LPD) is one of the most important aspects of an automatic license plate recognition system. Although there have been some successful license plate recognition (LPR) methods in past decades, it is still a challenging problem because of the diversity of plate formats and outdoor illumination conditions in image acquisition. Because the accurate detection of license plates...

A vehicle license plate recognition system extracts plate information from a digital image through image processing technology. License plate extraction (LPE) is the premise and key concept of license plate recognition systems. In China, two-row license plates are yellow and dirty. Thus, a novel license plate extraction method based on CIELab color space is proposed in this paper. The method in...

Technological intelligence is a highly sought after commodity even in traffic-based systems. These intelligent systems do not only help in traffic monitoring but also in commuter safety, law enforcement and commercial applications. In this paper, a license plate localization and recognition system for vehicles in Malaysia is proposed. This system is developed based on digital images and can be ...

The recognition of car license plates has a variety of applications ranging from surveillance, to access and traffic control, to law enforcement. Today a number of algorithms have been developed to extract car license plate numbers from imaging data. In general there two class of systems, one operating on triggered high speed cameras, employed in speed limit enforcement, and one based on video ...
