| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Image warping is an important visual effect tool in entertainment industry and other research field. The B-spline approximation is a powerful and useful warping algorithm. In order to minimize the warping error, a multi-level B-spline approximation has been proposed. Though a natural and smooth warped image can be obtained by using the multi-level B-spline approximation, it takes a large computation cost. In this paper, we proposed an adaptive lattice method to reduce the large computation cost and a partial transformation method for enhancement of the warping accuracy. The experimental results show that the proposed methods are more efficient and accurate than conventional multi-level B-spline method. | |
