Pose estimation for multiple camera systems

by Wen-yan Chang, Chu-song Chen - in: International Conference on Pattern Recognition
"... Pose estimation of a multiple camera system (MCS) is usually achieved by either solving the PnP problem or finding the least-squared-error rigid transformation between two 3D point sets. These methods employ partial information of an MCS, in which only a small number of features in one or two camera ..."

Scalable and Adaptable Tracking of Humans in Multiple Camera Systems

by A Gilbert , 2008
"... The aim of this thesis is to track objects on a network of cameras both within (intra) and across (inter) cameras. The algorithms must be adaptable to change and are learnt in a scalable approach. Uncalibrated cameras are used that are spatially separated, and therefore tracking must be able to cope ..."

H.: D-calib: Calibration software for multiple cameras system

by Yuko Uematsu, Tomoaki Teshima, Hideo Saito, Cao Honghua
"... This paper presents calibration software “D-Calib ” for multiple cameras, which can calibrate all cameras at the same time with easy operation. Our calibration method consists of two steps: initialization of camera parameters using planar marker pattern, optimization of initial param-eters by tracki ..."

A Multiple-Camera System Calibration Toolbox Using a Feature Descriptor-Based Calibration Pattern

by Bo Li , Lionel Heng , Kevin Köser , Marc Pollefeys - In Proceedings of the 2013 IEEE/RSJ International Conference on Intelligent Robots and Systems , 2013
"... Abstract-This paper presents a novel feature descriptorbased calibration pattern and a Matlab toolbox which uses the specially designed pattern to easily calibrate both the intrinsics and extrinsics of a multiple-camera system. In contrast to existing calibration patterns, in particular, the ubiqui ..."

An Investigation into the Feasibility of Real-time Soccer Offside Detection from a Multiple Camera System

by T. D’orazio (member Ieee, M. Leo, P. Spagnolo, P. L. Mazzeo, N. Mosca, M. Nitti, A. Distante
"... Abstract—In this work we investigate on the feasibility of multiple camera system for automatic offside detection. We propose six fixed cameras, properly placed on the two sides of the soccer field (three for each side) to reduce perspective and occlusion errors. The images acquired by the synchroni ..."

MonoSLAM: Realtime single camera SLAM

by Andrew J. Davison, Ian D. Reid, Nicholas D. Molton, Olivier Stasse - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2007
"... Abstract—We present a real-time algorithm which can recover the 3D trajectory of a monocular camera, moving rapidly through a previously unknown scene. Our system, which we dub MonoSLAM, is the first successful application of the SLAM methodology from mobile robotics to the “pure vision ” domain of ..."

Diagnosing multiple faults.

by Johan De Kleer , Brian C Williams - Artificial Intelligence, , 1987
"... Abstract Diagnostic tasks require determining the differences between a model of an artifact and the artifact itself. The differences between the manifested behavior of the artifact and the predicted behavior of the model guide the search for the differences between the artifact and its model. The ..."

in the domain of troubleshooting digital circuits. This research makes several novel contributions: First, the system diagnoses failures due to multiple faults. Second, failure candidates are represented and manipulated in terms of minimal sets of violated assumptions, resulting in an efficient diagnostic

Learning Patterns of Activity Using Real-Time Tracking

by Chris Stauffer, W. Eric L. Grimson - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 2000
"... Our goal is to develop a visual monitoring system that passively observes moving objects in a site and learns patterns of activity from those observations. For extended sites, the system will require multiple cameras. Thus, key elements of the system are motion tracking, camera coordination, activit ..."

Diversity and Multiplexing: A Fundamental Tradeoff in Multiple Antenna Channels

by Lizhong Zheng, David N. C. Tse - IEEE Trans. Inform. Theory , 2002
"... Multiple antennas can be used for increasing the amount of diversity or the number of degrees of freedom in wireless communication systems. In this paper, we propose the point of view that both types of gains can be simultaneously obtained for a given multiple antenna channel, but there is a fund ..."
