2.1.6 Recognition System of License Plate Using Multi-Experts
This is a thesis written by a master from China, Lu Xing De [15]. The purpose of
this thesis is to use the automatic technologies of image processing and computer vision
to develop an automatic license plate recognition system. In the proposed license plate
recognition system, rule-based technique is first employed to locate license plate. Then,
template matching is adopted to extract character image. Last, multiple experts is applied
to construct main recognition module for increasing the character recognition rate. In this
experiment, the vehicle images were taken on highway day and night (24hours).
Throughout this experiment, the license plate locating rate, character segmentation
successful rate, and character recognition rate in our system are all over 97%, and the
whole recognition rate is 92.8%. The table 2.1 shows the result of recognition system.
