Volume navigation is the interactive exploration of volume data sets by " flying " the view point through the data, producing a volume rendered view at each frame. In this paper, we present an inexpensive perspective volume navigation method designed to run on a PC platform with acceIerated 3D graphics hardware. We compute perspective projections at each… (More)

This paper addresses fast parallel methods for the computation of the Radon (Hough) Transform. The Radon Transform (RT) of an itnage is a set of projections of the image taken at different angles. Its computation is extremely important in image processing and computer vision, for problems such as pattern recognition ancl reconstruction of CAT scan images.… (More)

It is widely believed that the back propagation algorithm in neural networks, for tasks such as pattern classification, overcomes the limitations of the perceptron. We construct several counterexamples to this belief. We also construct linearly separable examples which have a unique minimum which fails to separate two families of vectors, and a simple… (More)

—Volume navigation is the interactive exploration of volume data sets by " flying " the viewpoint through the data, producing a volume rendered view at each frame. We present an inexpensive perspective volume navigation method designed to be run on a PC platform with accelerated 3D graphics hardware. The heart of the method is a two-phase perspective… (More)

This paper presents algorithms for routing channels with <?Pub Fmt italic>L<?Pub Fmt /italic>≥2 layers. For the unit vertical overlap model, we describe a two-layer channel routing algorithm that uses at most <inline-equation> <f> d+O<fen lp="par"><rad><rcd>d</rcd></rad><rp post="par"></fen> </f> </inline-equation> tracks to route two-terminal net… (More)

The technique of direct infusions into brain tissue of therapeutic molecules that would otherwise not adequately cross the blood–brain barrier (BBB) continues to be used in clinical trials. As part of our research into understanding the transport of fluids and molecules in brain tissue, we performed infusions of a saline solution of the magnetic resonance… (More)

This paper examines the problem of constructing dis-joint paths through a 3-dimensional grid in order to connect specified origin/destination terminal pairs so as to minimize the width of the grid. Specifi-callv. we nresent an algorithm which uses at most d/(i;'-p) ; O(pdm) rows, where L is the number of layers, p is the number of terminals per stack, and d… (More)
