Novel algorithm of searching color point-pairs to locate vehicle plate

The location of the vehicle plate is the core and most difficult technique in the vehicle plate auto-recognition system. In this paper, a novel algorithm of searching color point-pairs in locating vehicle plate is proposed. On the other hand, to decrease the time used to search the color point-pairs, the edge detection technique of image processing is used to pre-locate the areas the color point-pairs belong to. Through the experiment, it is proved that the algorithm proposed is valid and the results are satisfiable.
