| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we show scale-space properties of the boundary surfaces in three-dimensional Euclidean space which are derived on the basis of the differential geometry. The Canny operator approximately extracts the structure lines derived independently by Enomoto et al. and Krueger and Philips for planar grey-scale images. Analogous to their idea, Watanabe and Enomoto derived structure manifolds in three-dimensional Euclidean space. The performance of the Canny operator depends on the selection of the variance of the Gaussian kernel used in pre-smoothing for noise reduction. We examine the hierarchical properties of the structure surfaces in the Gaussian scale space of volumetric images to evaluate boundary-detection performances depending on the selection of scales, or the variances of the Gaussian kernel. We derive and observe a relationship between the boundary curves of slice images and the slices of the boundary manifolds. |
