Vehicle License-plate Recognition Based on Exponential Moments

Abstract

This paper proposed a new vehicle license-plate recognition algorithm based on exponential moments. In this paper, exponential moments' translation invariance, scaling invariance and rotation invariance were applied to the vehicle license-plate recognition. It has good recognition effect under the circumstance of license-plate inclined, and good at against weather changes and illumination insufficiency. This method can recognize the vehicle license-plate without tilt correction and proportional adjustment, which not only shorten the positioning time, but also proved the accuracy of the recognition.This research has good practical significance for future smart city contruction.
