Marginal Consistency: Unifying Constraint Propagation on Commutative Semirings
(Institute National de la Recherche Agronomique, 2008-09)We generalise the linear programming relaxation approach to Weighted CSP by Schlesinger and the max-sum diffusion algorithm by Koval and Kovalevsky twice: from Weighted CSP to Semiring CSP, and from binary networks to ... -
Matching with PROSAC – Progressive Sample Consensus
(IEEE, 2005-06)A new robust matching method is proposed. The progressive sample consensus (PROSAC) algorithm exploits the linear ordering defined on the set of correspondences by a similarity function used in establishing tentative ... -
Model Fitting Using RANSAC for Surgical Tool Localization in 3-D Ultrasound Images
(IEEE, 2010-08)Ultrasound guidance is used for many surgical interventions such as biopsy and electrode insertion. We present a method to localize a thin surgical tool such as a biopsy needle or a microelectrode in a 3-D ultrasound image. ... -
Model Selection for Automated Architectural Reconstruction from Multiple Views
(British Machine Vision Conference (BMVC), 2002-09)We describe progress in automatically fitting a plane plus modelled perturbation surface model to represent architectural scenes. There are two areas of novelty. The first is a method of fitting parametrized models in which ... -
Multi Modal Verification for Teleservices and Security Applications (M2VTS)
(IEEE, 1999-07)The paper presents the European ACTS project “M2VTS” which stands for Multi Modal Verification for Teleservices and Security Applications. The primary goal of this project is to address the issue of secured access to local ... -
A Multi-Frequency Approach to Increase the Native Resolution of Ultrasound Images
(IEEE, 2012)In ultrasound (US), a natural competition exists between the resolution of the image and the depth-of-field (DOF) into the medium, competition which is difficult to overcome with current US probe. Using large bandwidth ... -
Multi-resolution parallel integral projection for fast localization of a straight electrode in 3D ultrasound images
(IEEE, 2008-05)We address the problem of fast and accurate localization of miniature surgical instruments like needles or electrodes using 3D ultrasound (US). An algorithm based on maximizing a parallel integral transform (PIP) can ... -
Multimethod machine learning approach for medical diagnosing
(IEEE, 2003-04)In this paper we present a multimethod approach for induction of a specific class of classifiers, which can assist physicians in medical diagnosing in the case of mitral valve prolapse. Mitral valve prolapse is one of the ... -
Multiview 3D Tracking with an Incrementally Constructed 3D Model
(IEEE, 2006-06)We propose a multiview tracking method for rigid objects. Assuming that a part of the object is visible in at least two cameras, a partial 3D model is reconstructed in terms of a collection of small 3D planar patches of ... -
Neuromuscular fiber segmentation through particle filtering and discrete optimization
(SPIE, 2014)We present an algorithm to segment a set of parallel, intertwined and bifurcating bers from 3D images, targeted for the identi cation of neuronal bers in very large sets of 3D confocal microscopy images. The method ... -
Neuromuscular fiber segmentation using particle filtering and discrete optimization
(2012)We present an algorithm to segment a set of parallel, intertwined and bifurcating bers from 3D images, targeted for the identi cation of neuronal bers in very large sets of 3D confocal microscopy images. The method ... -
Non-Rigid Graph Registration using Active Testing Search
(2014)We present a new approach for matching sets of branching curvilinear structures that form graphs embedded in R2 or R3 and may be subject to deformations. Unlike earlier methods, ours does not rely on local appearance ... -
Number of arrhythmia beats determination in Holter electrocardiogram: How many clusters?
(IEEE, 2003-09)Holter signals correspond to long-term electrocardiograph (ECG) registers. Manual inspection of such signals is difficult because of the enormous quantity of beats involved. Throughout the literature several methods of ... -
Object-Detection With a Varying Number of Eigenspace Projections
(IEEE, 1998-08)We present a method allowing a significant speed-up of the eigen-detection method (detection based on principle component analysis). We derive a formula for an upper bound on the class-conditional probability (or equivalently ... -
On Combining Classifiers
(IEEE, 1998-03)We develop a common theoretical framework for combining classifiers which use distinct pattern representations and show that many existing schemes can be considered as special cases of compound classification where all the ... -
On the Interaction between Object Recognition and Colour Constancy
(IEEE, 2003)In this paper we investigate some aspects of the interaction between colour constancy and object recognition. We demonstrate that even under severe changes of illumination, many objects are reliably recognised if relying ... -
Online learning of robust object detectors during unstable tracking
(IEEE, 2009-09)This work investigates the problem of robust, longterm visual tracking of unknown objects in unconstrained environments. It therefore must cope with frame-cuts, fast camera movements and partial/total object occlusions/d ... -
Optimal Randomized RANSAC
(IEEE, 2008-08)A randomized model verification strategy for RANSAC is presented. The proposed method finds, like RANSAC, a solution that is optimal with user-specified probability. The solution is found in time that is close to the ... -
P-N Learning: Bootstrapping Binary Classifiers by Structural Constraints
(IEEE, 2010-06)This paper shows that the performance of a binary classifier can be significantly improved by the processing of structured unlabeled data, i.e. data are structured if knowing the label of one example restricts the labeling ... -
Parallel integral projection transform for straight electrode localization in 3-D ultrasound images
(IEEE, 2008-07)In surgical practice, small metallic instruments are frequently used to perform various tasks inside the human body. We address the problem of their accurate localization in the tissue. Recent experiments using medical ...
