Electrical conductivity imaging via contactless measurements

by Nevzat G. Gençer, M. Nejat Tek - IEEE TRANS. ON MED. IMAG , 1999
"... A new imaging modality is introduced to image electrical conductivity of biological tissues via contactless measurements. This modality uses magnetic excitation to induce currents inside the body and measures the magnetic fields of the induced currents. In this study, the mathematical basis of the ..."

A stereovision system for fire characteristics estimation

by Lucile Rossi, Moulay Akhloufi, Thierry Molinier, Yves Tison
"... This paper presents a stereovision system for the measurement of forest fire spread characteristics. Images of the scene are captured by a pre-calibrated stereo camera. A new approach is introduced in order to capture a three dimensional flame structure and to estimate important characteristics of t ..."

Camera Calibration and Three-Dimensional World Reconstruction of Stereo-Vision Using Neural Networks

by Qurban Memon, Sohaib Khan - International Journal of Systems Science , 2001
"... Camera calibration is considered as an important issue in computer vision. Accurate calibration of cameras is especially crucial for applications that involve quantitative measurements, depth from stereoscopy or motion from images. The problem of camera calibration is to compute the camera extrinsic ..."

Multi-view stereo reconstruction and scene flow estimation with a global image-based matching score

by Renaud Keriven, Olivier Faugeras - The International Journal of Computer Vision , 2006
"... Abstract. We present a new variational method for multi-view stereovision and non-rigid three-dimensional motion estimation from multiple video sequences. Our method minimizes the prediction error of the shape and motion estimates. Both problems then translate into a generic image registration task. ..."

, the starting step for the whole reconstruction procedure. The fitting parameters describing the geometric features composing the workpiece to be evaluated are used as quality measures to determine error bounds and finally to estimate the edge detection errors. These error estimates are then propagated up

Higher-Dimensional Multifractal Analysis

by Luis Barreira, Benoît Saussol, Jörg Schmeling , 2002
"... We establish a higher-dimensional version of multifractal analysis for several classes of hyperbolic dynamical systems. This means that we consider multifractal decompositions which are associated to multi-dimensional parameters. In particular, we obtain a conditional variational principle, which sh ..."

Markov Extensions For Multi-Dimensional Dynamical Systems

by Jérôme Buzzi, J Er Ome Buzzi - Israel J. Math , 1999
"... . By a result of F. Hofbauer [11], piecewise monotonic maps of the interval can be identified with topological Markov chains with respect to measures with large entropy. We generalize this to arbitrary piecewise invertible dynamical systems under the following assumption: the total entropy of th ..."

Dense Image Registration through MRFs and Efficient Linear Programming

by Ben Glocker , Nikos Komodakis , Georgios Tziritas , Nassir Navab , Nikos Paragios , 2008
"... In this paper we introduce a novel and efficient approach to dense image registration, which does not require a derivative of the employed cost function. In such a context the registration problem is formulated using a discrete Markov Random Field objective function. First, towards dimensionality re ..."

reduction on the variables we assume that the dense deformation field can be expressed using a small number of control points (registration grid) and an interpolation strategy. Then, the registration cost is expressed using a discrete sum over image costs (using an arbitrary similarity measure) projected
