Storage and executive processes in the frontal lobes.

by Edward E Smith , John Jonides - Science, , 1999
"... The human frontal cortex helps mediate working memory, a system that is used for temporary storage and manipulation of information and that is involved in many higher cognitive functions. Working memory includes two components: short-term storage (on the order of seconds) and executive processes th ..."

Lobes Many neuroimaging studies are founded on Baddeley's (7) model of working memory. In part, it posits separate storage buffers for verbal and visual-spatial information. Baddeley further argued that verbal storage can be decomposed into a phonological buffer for short-term maintenance

Unsupervised learning of models for recognition

by M. Weber, M. Welling, P. Perona - In ECCV , 2000
"... Abstract. We present a method to learn object class models from unlabeled and unsegmented cluttered scenes for the purpose of visual object recognition. We focus on a particular type of model where objects are represented as flexible constellations of rigid parts (features). The variability within a ..."

Improving the Fisher kernel for large-scale image classification.

by Florent Perronnin , Jorge Sánchez , Thomas Mensink - In ECCV, , 2010
"... Abstract. The Fisher kernel (FK) is a generic framework which combines the benefits of generative and discriminative approaches. In the context of image classification the FK was shown to extend the popular bag-of-visual-words (BOV) by going beyond count statistics. However, in practice, this enric ..."

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 ..."

Dynamic binding in a neural network for shape recognition

by John E. Hummel, Irving Biederman - Psychological Review , 1992
"... Given a single view of an object, humans can readily recognize that object from other views that preserve the parts in the original view. Empirical evidence suggests that this capacity reflects the activation of a viewpoint-invariant structural description specifying the object's parts and the ..."

Learning Invariance From Transformation Sequences

by Peter Földiák , 1991
"... Introduction How can we consistently recognize objects when changes in the viewing angle, eye position, distance, size, orientation, relative position, or deformations of the object itself (e.g., of a newspaper or a gymnast) can change their retinal projections so significantly? The visual system m ..."

must contain knowledge about such transformations in order to be able to generalize correctly. Part of this knowledge is probably determined genetically, but it is also likely that the visual system learns from its sensory experience, which contains plenty of examples of such transformations

Visual servo control Part I: basic approaches

by François Chaumette, Seth Hutchinson - IEEE ROBOTICS AND AUTOMATION MAGAZINE , 2006
"... This article is the first of a two-part series on the topic of visual servo control—using computer vision data in the servo loop to control the motion of a robot. In the present article, we describe the basic techniques that are by now well established in the field. We first give a general overview ..."

Dataflow Process Networks

by Edward A. Lee, Thomas Parks - Proceedings of the IEEE , 1995
"... We review a model of computation used in industrial practice in signal processing software environments and experimentally in other contexts. We give this model the name "dataflow process networks," and study its formal properties as well as its utility as a basis for programming language ..."

to functional languages such as Haskell, and show that modern language concepts such as higher-order functions and polymorphism can be used effectively in dataflow process networks. A number of programming examples using a visual syntax are given. This research is part of the Ptolemy project, whi...

Particle-based Magnetohydrodynamics Modeling and Visualization: Part II- Numerical Simulation

by Mihai Dupac
"... Abstract. In this paper a particle-base model is used to visualize results of the magnetohydrodynamics (MHD) phenomena related to electromagnetic levitation (EML) and magnetic stirring. Using the theoretical model presented in Part I, a numerical algorithm for fluid flow simulation has been describe ..."

Interactive Digital Photomontage

by Aseem Agarwala, Mira Dontcheva, Maneesh Agrawala, Steven Drucker, Alex Colburn, Brian Curless, David Salesin, Michael Cohen - ACM TRANS. GRAPH , 2004

Our framework makes use of two techniques primarily: graph-cut optimization, to choose good seams within the consti ..."
