Automatic thresholding of license plate

K Aboura - International Journal of Automation and Control, 2008 - inderscienceonline.com
Licence plate recognition (LPR) is a well studied problem first attempted in the 1970s. The
image analysis part in LPR renders the problem hard to solve perfectly, leading to continued …

Car License Plate Extraction Based on Detection of Numeral Regions

DR Lee, IS Oh - The Journal of The Korea Institute of Intelligent …, 2008 - koreascience.kr
In this paper we propose an algorithm to extract the license plate regions from Korean car
images. The idea of this paper is that we first find the four digits in the input car image and …
