176 Venkatasubramanian, SureshPower to the points: validating data memberships in clusteringsIn this paper, we present a method to attach affinity scores to the implicit labels of individual points in a clustering. The affinity scores capture the confidence level of the cluster that claims to "own" the point. We demonstrate that these scores accurately capture the quality of the label assig...2013-01-01
177 Gooch, Bruce; Reinhard, ErikPerception-driven black-and-white drawings and caricaturesIn this paper, we present a method for automatically creating black-and-white drawings of human faces from photographs. We then demonstrate new techniques for deforming these drawings to create caricatures intended to highlight and exaggerate facial features. A number of psychophysical studies we...Caricatures; Human faces2002-01-22
178 Carter, John B.AS-COMA: An adaptive hybrid shared memory ArchitectureScalable shared memory multiprocessors traditionally use either a cache coherent nonuniform memory access (CC-NUMA) or simple cache-only memory architecture (S-COMA) memory architecture. Recently, hybrid architectures that combine aspects of both CC-NUMA and S-COMA have emerged. In this paper, we pr...AS-COMA; Hybrid shared memory1998
179 Thompson, William B.; Willemsen, Peter; Gooch, Amy A.; Creem-Regehr, Sarah HopeDoes the quality of the computer graphics matter when judging distances in visually immersive environments?In the real world, people are quite accurate judging distances to locations in the environment, at least for targets resting on the ground plane and distances out to about 20m. Distance judgments in visually immersive environments are much less accurate. Several studies have now shown that in vis...Visually immersive environments2002-12-05
180 Hansen, Charles D.Interactive volume rendering using multi-dimensional transfer functions and direct manipulation widgetsMost direct volume renderings produced today employ one-dimensional transfer functions, which assign color and opacity to the volume based solely on the single scalar quantity which comprises the dataset.

185 Wald, Ingo; Shirley, Peter S.Geometric and arithmetic culling methods for entire ray packetsRecent interactive ray tracing performance has been mainly derived from the use of ray packets. Larger ray packets allow for significant amortization of both computations and memory accesses; however, the majority of primitives are still intersected by each ray in a packet. This paper discusses ...Ray tracing; Interval arithmetic; Ray packets; Frustum culling2006-08-16
186 Brunvand, Erik L.; Smith, Kent F.Self-timed design in GaAs - case study of a high-speed parallel multiplierAbstract-The problems with synchronous designs at high clock frequencies have been well documented. This makes an asynchronous approach attractive for high speed technologies like GaAs. We investigate the issues involved by describing the design of a parallel multiplier that can be part of a floati...1996
187 Brunvand, Erik L.Reduced latency self-timed FIFO circuitsSelf-timed flow-through FIFOs are constructed easily using only a single C-element as control for each stage of the FIFO. Throughput can be very high in FIFOs of this type because new data can be sent to the FIFO after communicating locally with only the first element of the FIFO. Therefore the thro...FIFO circuits; Self-timed; Flow-through; Reduced latency1994
188 Organick, Elliott I.Transformation of ADA programs into silicon (82 Mar. 1 - 82 Oct. 31)This report outlines the beginning steps taken in an integrated research effort toward the development of a methodology, and supporting systems, for transforming Ada programs, or program units, (directly) into corresponding VLSI systems.
