Independent Component Filters Of Natural Images Compared With Simple Cells In Primary Visual Cortex
, 1998
"... this article we investigate to what extent the statistical properties of natural images can be used to understand the variation of receptive field properties of simple cells in the mammalian primary visual cortex. The receptive fields of simple cells have been studied extensively (e.g., Hubel & ..."

Learning to detect objects in images via a sparse, part-based representation
- IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 2004
"... We study the problem of detecting objects in still, grayscale images. Our primary focus is development of a learning-based approach to the problem, that makes use of a sparse, part-based representation. A vocabulary of distinctive object parts is automatically constructed from a set of sample image ..."

Color-based probabilistic tracking
- ECCV
, 2002
"... Color-based trackers recently proposed in [3,4,5] have been proved robust and versatile for a modest computational cost. They are especially appealing for tracking tasks where the spatial structure of the tracked objects exhibits such a dramatic variability that trackers based on a space-dependent ..."

Phase relationship between hippocampal place units and the EEG theta rhythm. Hippocampus 3:317–330
, 1993
"... Many complex spike cells in the hippocampus of the freely moving rat have as their primary correlate the animal's location in an environment (place cells). In contrast, the hippocampal electroencephalograph theta pattern of rhythmical waves (7- 12 Hz) is better correlated with a class of moveme ..."

Qualitative Spatial Representation and Reasoning with the Region Connection Calculus
- PROCEEDINGS OF THE DIMACS INTERNATIONAL WORKSHOP ON GRAPH DRAWING, 1994. LECTURE NOTES IN COMPUTER SCIENCE
, 1997
"... This paper surveys the work of the qualitative spatial reasoning group at the University of Leeds. The group has developed a number of logical calculi for representing and reasoning with qualitative spatial relations over regions. We motivate the use of regions as the primary spatial entity and show ..."

The status of the Tropical Rainfall Measuring Mission (TRMM) after two years in orbit
- J. Appl. Meteorol
, 2000
"... This note is intended to serve primarily as a reference guide to users wishing to make use of the Tropical Rainfall Measuring Mission data. It covers each of the three primary rainfall instruments: the passive microwave radiometer, the precipitation radar, and the Visible and Infrared Radiometer Sys ..."

Multiresolution Sampling Procedure for Analysis and Synthesis of Texture Images
, 1998
"... This paper outlines a technique for treating input texture images as probability density estimators from which new textures, with similar appearance and structural properties, can be sampled. In a two-phase process, the input texture is first analyzed by measuring the joint occurrence of texture dis ..."

discrimination features at multiple resolutions. In the second phase, a new texture is synthesized by sampling successive spatial frequency bands from the input texture, conditioned on the similar joint occurrence of features at lower spatial frequencies. Textures synthesized with this method more successfully
G.: Primary production of the biosphere: Integrating terrestrial and oceanic components
- Science
, 1998
"... Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, with roughly equal contributions from land and oceans. Approaches based on satellite indices of absorbed s ..."

Space and attention in parietal cortex.
- Annual Review of Neuroscience,
, 1999
"... ABSTRACT The space around us is represented not once but many times in parietal cortex. These multiple representations encode locations and objects of interest in several egocentric reference frames. Stimulus representations are transformed from the coordinates of receptor surfaces, such as the ret ..."

The transformation is accomplished by dynamic updating of spatial representations in conjunction with voluntary movements. This direct sensory-to-motor coordinate transformation obviates the need for a single
