There is an increasing interest worldwide in animal detection systems to reduce animal-vehicle collisions. Traditional approaches include building animal crossings, introducing real or virtual fencing, video surveillance and break-the-beam systems. Unlike these approaches, the system described here Large Animal Warning and Detection System (LAWDS) employs a 360˚-scanning radar to monitor a stretch...
A common approach to approximating the medial axis decides the presence of medial points in a region of nonzero size by analyzing the gradient of the distance transform at a finite number of locations in this region. In general, algorithms of this type do not guarantee completeness. In this paper, we consider a novel medial axis approximation algorithm of this type and present an analysis in the 2D...
Medial surfaces are popular representations of 3D objects in vision, graphics and geometric modeling. They capture relevant symmetries and part hierarchies and also allow for detailed differential geometric information to be recovered. However, exact algorithms for their computation from meshes must solve high-order polynomial equations, while approximation algorithms rarely guarantee soundness and...
