| Summary: | 碩士 === 國立高雄第一科技大學 === 電腦與通訊工程所 === 96 === This thesis proposes a new license-plate recognition system. This new recognition system does not have the image pre-processing stage 、license-plate locating stage and the character segmentation stage. This new recognition system is suitable for community parking lot with some
controlled conditions.The 1-D non-recursive discrete periodized wavelet transform can derive the transformed coefficients with one single transformation. In this thesis,certain transformed coefficients are treated as license-plate features. And the new license-plate recognition system consists of the 1-D NRDPWT and
the back propagation neural network. The experimental results show the recognition rate can be as high as 94%.
