%X To locate vehicle license plate in complex circumstance, this paper put forward a new method of fast plate location based on Lab spaces color segmentation. First, it took full advantage of the red and green traits of hue component a in Lab color spaces to wipe off the interference of red and green. Second, utilized the blue and yellow character of b (another hue component in Lab color spaces) and the numerical difference between blue and yellow, to extract blue area and yellow area. Then it united the blue area and yellow area to realize location quickly. At last, it employed textures to locate blue and yellow plate precisely. The result shows that it is a fast and accurate license plate location method.
