A Robust and Efficient Approach to License Plate Detection
IEEE Transactions on Image Processing, 2017This paper presents a robust and efficient method for license plate detection with the purpose of accurately localizing vehicle license plates from complex scenes in real time. A simple yet effective image downscaling method is first proposed to substantially accelerate license plate localization without sacrificing detection performance compared with ...

License plate detection algorithm
SPIE Proceedings, 2013A novel algorithm for vehicle license plates localization is proposed. The algorithm is based on pixel intensity transition gradient analysis. Near to 2500 natural-scene gray-level vehicle images of different backgrounds and ambient illumination was tested. The best set of algorithm’s parameters produces detection rate up to 0.94.

Robust license plate detection in the wild
2017 14th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2017License Plate Detection (LPD) is the pivotal step for License Plate Recognition. In this work, we explore and customize state-of-the-art detection approaches for exclusively handling the LPD in the wild. In-the-wild LPD considers license plates captured in challenging conditions caused by bad weathers, lighting, traffics, and other factors.

An Autonomous License Plate Detection Method
2009 Fifth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2009Detection of license plate is an important process in intelligent transportation systems before license plate recognition. In this paper, we proposed an autonomous license plate detection system with computer vision instead of sensors. Using characteristics of dynamic images, our system rapidly identifies the license plate region.

Heuristic approach for license plate detection
Proceedings. IEEE Conference on Advanced Video and Signal Based Surveillance, 2005., 2006The license plate detection is one of the most important processes in license plate recognition (LPR) system. A number of techniques have been proposed in research literatures. Among the most promising techniques is text locating-based technique. However, in a complex scene the technique creates too many candidate regions with noisy background which ...

Automatic License Plate Detection System for Myanmar Vehicle License Plates
2019 International Conference on Advanced Information Technologies (ICAIT), 2019License Plate Detection is an intelligent system to find the exact license plate by analyzing image/video data for automatic license plate recognition (ALPR) system. The proposed system used image data. There is much early research has been done for ALPR purposes, however, it was still challenging tasks for accurately detect license plates in the open ...

Detecting, Tracking and Recognizing License Plates
2007This paper introduces a novel real-time framework which enables detection, tracking and recognition of license plates from video sequences. An efficient algorithm based on analysis of Maximally Stable Extremal Region (MSER) detection results allows localization of international license plates in single images without the need of any learning scheme ...

Rectangular Shape Detection with an Application to License Plate Detection
2013 IEEE 25th International Conference on Tools with Artificial Intelligence, 2013Rectangular shape detection has a wide range of applications, such as license plate detection, vehicle detection and building detection. In this paper, we propose a robust framework for rectangular shape detection based on the channel-scale space of RGB images. The framework consists of algorithms developed to address two issues of a shape attention (i.

A Fast Algorithm for License Plate Detection
2007In this paper we propose a method for detection of the car license plates in 2D gray images. In this method we first estimate the density of vertical edges in the image. The regions with high density vertical edges are good candidates for license plates.
