Research and Implementation of Vehicle-logo Recognition Based on Modified Invariant Moments

摘要

According to the low recognition rate of Hu invariant moments in the target images, this article proposes a vehicle-logo recognition research algorithm based on the modified invariant moments. At first, use the template matching to locate the vehicle-logo rough area and use the edge detection for accurate location. Then, calculate the characteristic value of the modified invariant moments of the vehicle-logo, finally, the vehicle-logo is recognized according to the minimum distance of invariant moments. The experimental results show that the modified invariant moments can improve the recognition rate of target images effectively.
