Pictorial Structures for Object Recognition

by Pedro F. Felzenszwalb, Daniel P. Huttenlocher - IJCV , 2003
"... In this paper we present a statistical framework for modeling the appearance of objects. Our work is motivated by the pictorial structure models introduced by Fischler and Elschlager. The basic idea is to model an object by a collection of parts arranged in a deformable configuration. The appearance ..."

A Hierarchical Internet Object Cache

by Anawat Chankhunthod , Peter B. Danzig, Chuck Neerdaels, Michael F. Schwartz, Kurt J. Worrell - IN PROCEEDINGS OF THE 1996 USENIX TECHNICAL CONFERENCE , 1995
"... This paper discusses the design andperformance of a hierarchical proxy-cache designed to make Internet information systems scale better. The design was motivated by our earlier trace-driven simulation study of Internet traffic. We believe that the conventional wisdom, that the benefits of hierarch ..."

of magnitude under concurrent load. These measurements indicate that hierarchy does not measurably increase access latency. Our software can also be configured as a Web-server accelerator; we present data that our httpd-accelerator is ten times faster than Netscape's Netsite and NCSA 1.4 servers. Finally

Pastry: Scalable, distributed object location and routing for large-scale peer-to-peer systems

by Antony Rowstron, Peter Druschel , 2001
"... This paper presents the design and evaluation of Pastry, a scalable, distributed object location and routing scheme for wide-area peer-to-peer applications. Pastry provides application-level routing and object location in a potentially very large overlay network of nodes connected via the Internet. ..."

Pastry is completely decentralized, scalable, and self-configuring; it automatically adapts to the arrival, departure

Generative models for labeling multi–object configurations in images

by Yali Amit, Alain Trouvé , 2007
"... Abstract. We propose a generative approach to the problem of labeling images containing configurations of objects from multiple classes. The main building blocks are dense statistical models for individual objects. The models assume conditional independence of binary oriented edge variables conditio ..."

A Spectral Attentional Mechanism Tuned to Object Configurations

by C. L. Lin
"... Abstract — This paper describes an attentional mechanism based on the interpretation of spectral signatures for detecting regular object configurations in areas of an image delineated using context information. The proposed global operator relies on the spectral analysis of edge structure and exploi ..."

Recognition-by-components: A theory of human image understanding

by Irving Biederman - Psychological Review , 1987
"... The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory, recog ..."

by human observers provide empirical support for the theory. Any single object can project an infinity of image configura-tions to the retina. The orientation of the object to the viewer can vary continuously, each giving rise to a different two-dimen-sional projection. The object can be occluded by other

The Ponder Policy Specification Language

by Nicodemos Damianou , Naranker Dulay , Emil Lupu , Morris Sloman - LECTURE NOTES IN COMPUTER SCIENCE , 2001
"... The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management ..."

These reusable composite policy specifications cater for the complexity of large enterprise information

The serial cultivation of human diploid cell strains. Exp Cell Res

by L. Hayflick, P. S. Moorhead , 1961
"... ONLY limited success has been obtained in developing strains of human cells that can be cultivated for long periods of time in vitro and that still preserve the diploid chromosomal configuration [41, 47, 48, 58, 591. Indeed, heteroploidy may be a necessary corollary or even the cause of the altera-t ..."

A Representation Scheme for Description and Reconstruction of Object Configurations Based on Qualitative Relations

by H. Joe Steinhauer
"... One reason Qualitative Spatial Reasoning (QSR) is becoming increasingly important to Artificial Intelligence (AI) is the need for a smooth ‘human-like’ communication between autonomous agents and people. The selected, yet general, task motivating the work presented here is the scenario of an object ..."

configuration that has to be described by an observer on the ground using only relational object positions. The description provided should enable a second agent to create a maplike picture of the described configuration in order to recognize the configuration on a representation from the survey perspective

Understanding Line Drawings of Scenes with Shadows

by David Waltz - The Psychology of Computer Vision , 1975
"... this paper, how can we recognize the identity of Figs. 2.1 and 2.2? Do we use' learning and knowledge to interpret what we see, or do we somehow automatically see the world as stable and independent bf lighting? What portions of scenes can we understand from local features alone, and what confi ..."

configurations require the use of 1obal hypotheses? 19 In this essay I describe a working collection of computer programs which reconstruct three-dimensional descriptions from line drawings which are obtained from scenes composed of plane-faced objects under various lighting conditions. The system identifies
