METHOD FOR RECOGNIZING LICENSE PLATE IMAGE, AND RELATED COMPUTER PROGRAM PRODUCT, COMPUTER-READABLE RECORDING MEDIUM, AND IMAGE RECOGNIZING APPARATUS USING THE SAME
First Claim
1. A computer implemented method of recognizing a license plate image, comprising:
- collecting a plurality of character template images;
respectively homogenizing the character template images to generate a plurality of simulated character template images based on the license plate image;
respectively generating a plurality of similarity degrees corresponding to the simulated character template images by comparing the simulated character template images with the license plate image;
estimating at least one candidate character corresponding to the license plate image and at least one candidate character position corresponding to the at least one candidate character according to the similarity degrees corresponding to the simulated character template images.

Abstract
A computer implemented method for recognizing license plate image, and related computer product, computer-readable recording medium, and image recognizing apparatus using the same is provided. The method includes collecting a plurality of character template images and respectively homogenizing the character template images to generate a plurality of simulated character template images based on the license plate image. The method also includes respectively generating a plurality of similarity degrees corresponding to the simulated character template images by comparing the simulated character template images with the license plate image. The method further includes estimating at least one candidate character corresponding to the license plate image and at least one candidate character position corresponding to the at least one candidate character according to the similarity degrees corresponding to the simulated character template images. Accordingly, the method can effectively recognize license plate numbers in a license plate image.
