This paper presents a heuristic triangulation algorithm for reconstructing surfaces over a set of cross-sectional contours. The multiple branching problem, an important problem of conventional triangulation methods, is treated as a set of double branchings, and an algorithm based on contour merging is developed. Several imaginary contours are generated to handle the multiple branching problem with many branch contours. A double branching algorithm based on the partitioning of the root contour is also proposed. The results show that our method works well even for objects with many complicated branches.
We developed a facial color change technique, which is a combination of emotional models based on human cultural theory, emotional expression pattern using colors, and emotional reaction speed function, as opposed to previous methods that express emotions through blood flow, pulse, or skin temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
