Choices, values and frames.

by Daniel Kahneman - American Psychologist, , 1984
"... Making decisions is like speaking prose-people do it all the time, knowingly or unknowingly. It is hardly surprising, then, that the topic of decision making is shared by many disciplines, from mathematics and statistics, through economics and political science, to sociology and psychology. The stu ..."

's analysis, consider the choice between a prospect that offers an 85% chance to win $1000 (with a 15% chance to win nothing) and the alternative of receiving $800 for sure. A large majority of people prefer the sure thing over the gamble, although the gamble has higher (mathematical) expectation

Alternative isoform regulation in human tissue transcriptomes

by Eric T. Wang, Rickard S, Shujun Luo, Irina Khrebtukova, Lu Zhang, Christine Mayr, Stephen F. Kingsmore, Gary P. Schroth, Christopher B. Burge - Nature , 2008
"... Through alternative processing of pre-mRNAs, individual mammalian genes often produce multiple mRNA and protein isoforms that may have related, distinct or even opposing functions. Here we report an in-depth analysis of 15 diverse human tissue and cell line transcriptomes based on deep sequencing of ..."

-specific read densities indicated that a majority of AS and of alternative cleavage and polyadenylation (APA) events vary between tissues, while variation between individuals was ∼2- to 3-fold less common. Extreme or ‘switch-like ’ regulation of splicing between tissues was associated with increased sequence

Human Motion Analysis: A Review

by J. K. Aggarwal, Q. Cai - Computer Vision and Image Understanding , 1999
"... Human motion analysis is receiving increasing at-tention from computer vision researchers. This inter-est is motivated by a wide spectrum of applications, such as athletic performance analysis, surveillance, man-machine interfaces, content-based image storage and retrieval, and video conferencing. T ..."

. This paper gives an overview of the various tasks involved in motion analysis of the human body. We focus on three major areas related to interpreting human motion: 1) motion analysis involving human body parts, 2) tracking of human motion wing single or multiple cameras, and 8) recognizing human activities

Computer Vision Face Tracking For Use in a Perceptual User Interface

by Gary R. Bradski , 1998
"... As a first step towards a perceptual user interface, a computer vision color tracking algorithm is developed and applied towards tracking human faces. Computer vision algorithms that are intended to form part of a perceptual user interface must be fast and efficient. They must be able to track in re ..."

in real time yet not absorb a major share of computational resources: other tasks must be able to run while the visual interface is being used. The new algorithm developed here is based on a robust nonparametric technique for climbing density gradients to find the mode (peak) of probability distributions

Visibility Preprocessing For Interactive Walkthroughs

by Seth J. Teller, Carlo H. Sequin - IN: COMPUTER GRAPHICS (SIGGRAPH 91 PROCEEDINGS , 1991
"... The number of polygons comprising interesting architectural models is many more than can be rendered at interactive frame rates. However, due to occlusion by opaque surfaces (e.g., walls), only a small fraction of atypical model is visible from most viewpoints. We describe a method of visibility pre ..."

Interactive Multi-Resolution Modeling on Arbitrary Meshes

by Leif Kobbelt , Swen Campagna, Jens Vorsatz, Hans-Peter Seidel , 1998
"... During the last years the concept of multi-resolution modeling has gained special attention in many fields of computer graphics and geometric modeling. In this paper we generalize powerful multiresolution techniques to arbitrary triangle meshes without requiring subdivision connectivity. Our major o ..."

Slipping into and out of Poverty: The Dynamics of Spells

by Mary Jo Bane, David T. Ellwood - Journal of Human Resources , 1986
"... This paper examines the dynamics of poverty. Previous analyses have examined either fluctuations in the male heads ' eamings or the frequency of poverty periods over a fixed time frame. Our approach depends on a definition of spells of poverty. Using this methodology we find that the majority o ..."

Painterly Rendering for Animation

by Barbara J. Meier - 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 ..."

Real-Time Nonphotorealistic Rendering

by Lee Markosian , Michael A. Kowalski, Samuel J. Trychin, Lubomir D. Bourdev, Daniel Goldstein, John F. Hughes , 1997
"... Nonphotorealistic rendering (NPR) can help make comprehensible but simple pictures of complicated objects by employing an economy of line. But current nonphotorealistic rendering is primarily a batch process. This paper presents a real-time nonphotorealistic renderer that deliberately trades accurac ..."
Abstract - Cited by 174 (10 self) - Add to MetaCart
visibility has the potential to be used in any NPR system that requires a description of visible lines or surfaces in the scene. The major contribution of this paper is thus to describe a tool which can significantly improve the performance of these systems. We demonstrate the system with several

A classification of natural rivers.

by David L Rosgen - Catena , 1994
"... Abstract A classification system for natural rivers is presented in which a morphological arrangement of stream characteristics is organized into relatively homogeneous stream types. This paper describes morphologically similar stream reaches that are divided into 7 major stream type categories tha ..."
