The point in polygon problem for arbitrary polygons
Kai Hormann,Alexander Agathos +1 more
TL;DR: It is shown by mathematical means that both concepts for solving the point in polygon problem for arbitrary polygons are very closely related, thereby developing a first version of an algorithm for determining the winding number.
Journal ArticleDOI
Minimum Volume Simplex Analysis: A Fast Algorithm for Linear Hyperspectral Unmixing
TL;DR: This paper describes a method for unsupervised hyperspectral unmixing called minimum volume simplex analysis (MVSA) and introduces a new computationally efficient implementation and observes that MVSA yields competitive performance when compared with other available algorithms that work under the nonpure pixel regime.
Journal ArticleDOI
3D Mesh Segmentation Methodologies for CAD applications
TL;DR: A classification of the various methods of 3D mesh segmentation based on their corresponding underlying fundamental methodology concept as well as on the distinct criteria and features used in the segmentation process is given.
Journal ArticleDOI
Geosemantic Snapping for Sketch-Based Modeling
TL;DR: This paper proposes a method to model 3D objects from sketches by utilizing humans specifically for semantic tasks that are very simple for humans and extremely difficult for the machine, while utilizing the machine for tasks that is harder for humans.
Journal ArticleDOI
Robust Minimum Volume Simplex Analysis for Hyperspectral Unmixing
TL;DR: This paper develops a linearization relaxation of the nonlinear chance constraints, which can greatly lighten the computational complex of chance constraint problems.
