Detection of License Plates of Vehicles

چکیده
This paper presents an image processing approach for the detection of the vehicle license plate area in digitized photographic images. The algorithm takes a raster image of the rear view of a vehicle as input and yields the segment of the photograph that contains the plate as the output. The developed algorithm is based on three basic processing stages; yellow regions extraction, dilation of yellow regions and extraction of the plate region. The performance of the developed algorithm has been tested on a set of real images of vehicles. Preliminary tests show that the algorithm performs quite well in accurately locating the license plates (with 97% efficiency). The results of this work can be extended for the automatic detection and recognition of vehicle license plates for vehicle identification.

A license plate recognition system contains three main steps: plate detection, character segmentation and character recognition. The first and foremost step of this system is the plate detection stage where the plate is located from the input image. In this paper an effective plate detection approach is developed based on a cascade classifier. A two-phase training approach is proposed to enhanc...

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...
