| Abstract: | Number plate extraction is the key component of automatic vehicle license recognition system. Several important features of standard number plate are designed and extracted in this paper, and the problem of extracting number plate under complex background is resolved using the mathematic morphological operation, shape measurement of connected area and color image analysis, thereafter putting right the slant plate and getting rid of the outer bounding frame and rivet, finally extract the separate car license character. The experiment result shows that the proposed approach is good enough to be put into practical use, with respect to real time, robustness and accuracy. |
| Keywords: | measurement of connected area color image analysis extraction of number plate |
