The Census transform is very useful in stereo matching algorithms. But the traditional Census transform cost too much computation, and its accuracy and robustness are not satisfying. In this paper, a modified semi-global matching (SGM) algorithm based on the fast Census transform is proposed to improve the quality of the range map and decrease the(More)
Man-made objectivity always exits in traditional fuzzy comprehensive evaluation for the weights of the evaluation factors are setting by us. This paper introduces a new fuzzy comprehensive evaluation based on the catastrophe theory and factor analysis, which has just to consider the relative importance without computing the calculation details. So the final(More)
A new definition on the distance of fuzzy number based on structured element is proposed, which overcomes the shortcomings that the fuzzy numbers is real numbers. It also proves that the distance meets the axiomatic definition of fuzzy metric. And the membership of special fuzzy distance is given in this paper. A brief analysis of the mathematical nature(More)
