| Abstract(in English) | The goal of our research is to extract and display the topological structure of observed objects from multidimensional digital images. Contour Tree can describe the topological relationship among isosurfaces in scalar field. Conventional methods to construct the Contour Trees are limited for scalar fields expressed by multidimensional meshes, and several problems occur when we apply these methods to digital images. Moreover, it is difficult for users to interpret the Contour Trees when the displayed tree structures are complicated. In order to construct the Contour Trees from digital images, we extend a procedure proposed by Carr et al. In the proposed method, we introduce the different types of pixel (voxel) connectivity for foreground and background regions. To display the Contour Trees more intuitively, we also propose a new method named Contour Nest. The method transforms the tree structure into a nest structure of two-dimensional rectangles. |
