Vehicle License Plate Location and Rectification Algorithms Based on RGB Chroma Space

A new approach is presented for vehicle license plate location and rectification based on RGB chroma space in the complicated-background and different illumination images.According to the character of RGB chroma space,a vehicle plate location model was built through a series of operations in RGB chroma space.Experimental results show that the vehicle license plate location and rectification algorithms based on RGB chroma space can improve the whole performance of vehicle license plate recognition system greatly.
