| Abstract: | In accordance with the special circumstance of the toll gate, based on the new method of edge detection and image binarization, this paper proposes a new algorithm for license-plate location and characters segmentation only applying the characteristic of license-plate. Having been monitored and inspected on the toll line, this algorithm is excellent in the accuracy and the robustness. The proper license plate locating rate is 98.7%, and the proper character segmentation accuracy reaches 99%. |
