A Method of Multi-License Plate Location in Road Bayonet Image
نویسندگان
چکیده
To solve the problem of multi-license plate location in road bayonet image, a novel approach was presented, which utilized plate’s color features, geometry characteristics and gray feature. Firstly, the RGB color image was converted to HSV color model and calculates the distance according to the plate’s color information in the color space. Secondly, the license plate candidate regions were segmented by binary and morphological processing. Finally, based on the plate’s geometry characteristics and gray feature, the license plate regions were segmented by and validated. In a certain degree, the method wasn’t limited the plate’s type, size, number, the location of the car and the background in the picture. It was tested using the road bayonet image.(Abstract) Keywords—multi-license plate location; color features; geometry characteristics; gray feature

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...

License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...

License plate recognition (LPR) by using morphology has the advantage of resistance to brightness changes; high speed processing, and low complexity. However these approaches are sensitive to the distance of the plate from the camera and imaging angle. Various assumptions reported in other works might be unrealistic and cause major problems in practical experiences. In this paper we considered ...

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...
