Title:
A METHOD FOR BINARISING LICENSE PLATE
Document Type and Number:
WIPO Patent Application WO/2019/066643
Kind Code:
A3
Abstract:
The present invention relates to a method for binarising license plate. The method includes the steps of filtering noises in an image of the license plate, correcting the orientation of the image of the license plate, portioning the image of the plate into two pairs of sub-images, computing histograms of pixel intensity for all the sub-images, defining range of interest for each histogram, computing cross-bin histogram similarity measurement, determines whether the similarity measurement is higher than a certain threshold, adapting a local binarisation if the similarity score is higher than the threshold, recognising individual entity of the plate and transforming individual entity of the license plate into the text format of alphabet and number, and analysing all the recognised entity in order to determine the final context of the plate.
