License Vehicle Plates Localization Using Maximum Correlation
In this paper we propose an automatic method to locate Brazilian license plates in digital images acquired from a real monitoring traffic system. The approach is based on the correlation between lines of the preprocessed image and a square wave form that resembles lines in the region of the pattern plate. The maximum correlation points out the horizontal and vertical crossing axes over the plate. Prior to locating plates, the post processing Min/Max scheme is applied to the binary images in order to diffuse segmentation remnant noise.
