Study on Object Location Fusion Algorithm of Actual License Plate Images

The vehicle license plate (VLP) location is the key technique of the vehicle license plate recognition system. The region of license plate has rich edge information and fixed color feature. The location method fusing gray edge and color feature is more accurate and easier than the method only in gray space or in color space. The experiments on 200 Chinese automobile RGB real color images taken from traffic stations under various conditions show that the correct location rate is over 99 percent.
