Visual search
- In H. Pashler (Ed.), Attention
, 1998
"... This paper describes a series of visual search experiments for targets defined by their hinocu-lar characteristics. In searches for targets defined by binocular rivalry among fused distractors, or vice versa, the rivalrous items do not "pop out " (reaction time [RT] increases with number o ..."

of distractors). Binocular luster, a variety of rivalry, is an exception. Luster, an important property of visible surfaces, behaves like a basic feature or "texton " (RT independent of the number of nonlustrous distractors). Searches for targets defined exclusively by eye-of-origin information
Painterly Rendering for Animation
- In SIGGRAPH 96 Conference Proceedings
, 1996
"... We present a technique for rendering animations in a painterly style. The difficulty in using existing still frame methods for animation is getting the paint to “stick ” to surfaces rather than randomly change with each frame, while still retaining a hand-crafted look. We extend the still frame meth ..."

technique provides for frame-to-frame coherence in animations so that the resulting frames do not randomly change every frame. To maintain coherence, we model surfaces as 3d particle sets which are rendered as 2d paint brush strokes in screen space much like an artist lays down brush strokes on a canvas. We
Display Methods for Grey-Scale, Voxel-Based Data Sets
"... The dramatic increase in the use of 3D image acquisition devices over the past decade has inspired major new developments in the display of volume data sets. In this chapter we present an overview of these diverse display methods and discuss the relative advantages and disadvantages of each of the d ..."

from volume data, there has not yet emerged any widely accepted taxonomy for these methods. Because the human visual system is adapted for environments in which images of surfaces predominate, most algorithms emphasize in one way or another the display of surface-like information, either implicitly
Feature Sensitive Surface Extraction from Volume Data
"... The representation of geometric objects based on volumetric data structures has advantages in many geometry processing applications that require, e.g., fast surface interrogation or boolean operations such as intersection and union. However, surface based algorithms like shape optimization (fairing) ..."

Evidence for and implications of self-healing pulses of slip in earthquake rupture, Phys. Earth Planet Int
, 1990
"... Heaton, T.H., 1990. Evidence for and implications of self-healing pulses of slip in earthquake rupture. Phys. Earth Planet. Inter., 64: 1—20. Dislocation time histories of models derived from waveforms of seven earthquakes are discussed. In each model, dislocation rise times (the duration of slip fo ..."

Covariance scaled sampling for monocular 3D body tracking
- CVPR
, 2001
"... We present a method for recovering 3D human body motion from monocular video sequences using robust image matching, joint limits and non-self-intersection constraints, and a new sample-andrefine search strategy guided by rescaled cost-function covariances. Monocular 3D body tracking is challenging: ..."

-observability make the parameter-space cost surface multi-modal, unpredictable and illconditioned, so minimizing it is difficult. We discuss the limitations of CONDENSATION-like samplers, and introduce a novel hybrid search algorithm that combines inflated-covariance-scaled sampling and continuous optimization
iLamps: Geometrically aware and self-configuring projectors
- ACM TOG
, 2003
"... Projectors are currently undergoing a transformation as they evolve from static output devices to portable, environment-aware, communicating systems. An enhanced projector can determine and respond to the geometry of the display surface, and can be used in an ad-hoc cluster to create a self-configur ..."

This paper examines geometrical issues for enhanced projectors, relating to customized projection for different shapes of display surface, object
Prediction, conservation analysis and structural characterization of mammalian mucin-type O-glycosylation sites
- Glycobiology
, 2005
"... O-GalNAc-glycosylation is one of the main types of glycosy-lation in mammalian cells. No consensus recognition sequence for the O-glycosyltransferases is known, making prediction methods necessary to bridge the gap between the large num-ber of known protein sequences and the small number of proteins ..."

Estimating Articulated Human Motion With Covariance Scaled Sampling

We present a method for recovering 3D human body motion from monocular video sequences based on a robust image matching metric, incorporation of joint limits and non-self-intersection constraints, and a new sample-and-refine search strategy guided by rescaled cost-function covariances.

The nonlinearities and matching ambiguities make the parameter-space cost surface multi-modal, ill-conditioned and highly
A progressive multi-pass method for global illumination

The method combines the existing methods of progressive refinement radiosity, Monte Carlo path tracing and light ray tracing. The me ..."
