An Algorithm of Quick Location for License Plate

A fast and precise location is a key step in the real-time and automatic recognition techniques for license plate. A license plate location algorithm based on the combination of edge detection and projection and another algorithm based on the combination of binarization and projection are put forward by means of the characteristics in sizes, interval, number and type of the characters on license plate. Large amounts of experimental results demonstrate that both algorithms have the properties of rapidity, simplicity, applicability and a small dependence with a complicated image background.
