A hybrid Indian license plate character segmentation algorithm for automatic license plate recognition system

摘要

A hybrid character segmentation algorithm is proposed here involving license plate normalization and object enhancement technique as an image preprocessing step, followed by Hough transformation based horizontal and vertical segmentation steps for Indian LP Character segmentation. Character segmentation is an important step in Automatic License Plate Recognition (ALPR) system. The hybrid algorithm addresses many difficulties present in this step, such as the influence of image noise, plate frame, rivet, the space mark, and so on. The experiment results show a good performance of this new segmentation algorithm.
