A New Approach for License Plate Detection and Localization: Between Reality and Applicability

Abstract

<p>License Plate Detection and Localization (LPDL) is known to have become one of the most progressive and growing areas of study in the field of Intelligent Traffic Management System (ITMS). LPDL provides assistance by being able to specifically locate a vehicle’s number plate which is an essential part of ITMS, that is used for automatic road tax collection, traffic signals defilement implementation, borders and payments barriers and to monitor unlike activities. Organizations can deploy the number plate detection and recognition system to track their vehicles and to monitor each of them in their vital business activities like inbound and outbound logistics, find the exact location of their vehicles and organize entrance management. A competent algorithm is proposed in this paper for number plate detection and localization based on segmentation and morphological operators. Thus, the proposed algorithm it works on enhancing the quality of the image by applying morphological operators afterwards to segment out license plate from the captured image. No assumptions about the license plate color, style of font, size of text and type of material the plate is made of. The results reveal that the proposed algorithm works perfectly on all kinds of license plates with 93.43% efficiency rate. </p>

Automatic License Plate Detection and Recognition for Jordanian Vehicles

“…• The processing time for detecting the license plate and recognizing the plate numbers in both [12] and [13] was not reported at all, whereas in the proposed work it is being reported.…”

“…In [12], the authors proposed a number plate detection and localization system based on segmentation and morphological operators to segment out license plate from the captured image. Specifically, the authors used histogram checking, and vertical and horizontal edge detection methods for the segmentation of the license plate.…”

“…After surveying the literature and to the best of our knowledge, the work of [2,12,13] is the only published work that examines the detection and recognition of the license plates of the Jordanian vehicles. Therefore, the work presented in this paper extends the literature regarding the Jordanian license plates detection and recognition.…”

“…Furthermore, the recognition of vehicle logo and make was also incorporated. It is worth mentioning the notes concerning the work by authors in [12] and [13]:…”

“…• Neither the work in [12] nor in [13] presented a fully comprehensive ANPR system, where both the license plate type (private, public, government, etc.) and the vehicle's make are being recognized similar to what are being implemented in the proposed work.…”
