  • 지난 8우러부터 자동차보험료가 평균 3.8%가 인상됨에 따라 보험 계약자들의 부담이 그만큼 커졌다. 그러나 보험료 자율화에 따라 보험사간에 치열한 경쟁으로 보험료를 할인 판매하는 보험사도 나타나고 있어, 보험가입시 잘 따지고, 살피면, 어느 정도 자동차 보험을 절약할 수 있을 것이다. 이번호에는 자동ㅊ차보험료를 절약할 수 있는 방법에 대해 소개하고자 한다.

  • License plate recognition is an active research area. but few comparative studies on license plate binarization have been conducted. Many related researchers have experienced similar trial and error for finding an effective binarization method. To reduce this trial and error, this study implemented some binarization methods and quantitatively compared the performance of the methods. The performance evaluation consists of a low level measure and a high level measure, so it can evaluate not only the quality of binarized image itself but also the usefulness of the result. The performance evaluation was separately performed with three groups of images so as to understand the properties of the binarization methods. Experimental results show that the quality of binarization is more dependent on the evenness of illumination than the intensity of illumination. The Otsu's method has acquired the most effective performance in the group of even illumination images and the Niblack's method with parameter correction has shown the best quality in the group of uneven illumination images.
