| Abstract(in English) | In our previous work, we proposed a fast algorithm to calculate the similarity of B-spline curves. Although the proposed method is a linear time algorithm, it has room for improvement in accuracy due to the constraint that the start points and the end points of two curves must match. In this paper, we try to improve the accuracy of the proposed algorithm by eliminating this constraint. We also verify that the proposed method is faster and more accurate than the conventional method through numerical experiments. |
