Abstract:For the location of multiple License Plates in video streams, this paper presented an effective method of Multi-license plates location based on image restoration and HSV color model. The main idea of this method was to use an improved Wiener filter to get the video image recovery. And then in HSV color space, it constructed a five-scale gray image according to the color characteristics of license plate, and used the morphology smooth to eliminate noise. Finally, the potential region of the plate was segmented through horizontal and vertical projection value and we got the accurate position of the multiple plates by prior knowledge of the car-plate region. Experimental results show that the proposed method can extract multiple motive license plates exactly from a complex background.
