Registration of segmented histological images using thin plate splines and belief propagation
(SPIE, 2014)We register images based on their multiclass segmentations, for cases when correspondence of local features cannot be established. A discrete mutual information is used as a similarity criterion. It is evaluated at a sparse ... -
Revisiting the Decomposition Approach to Inference in Exponential Families and Graphical Models
(Center for Machine Perception, Department of Cybernetics, Faculty of Electrical Engineering, Czech Technical University, 2009-05) -
Revisiting the Linear Programming Relaxation Approach to Gibbs Energy Minimization and Weighted Constraint Satisfaction
(IEEE, 2010)We present a number of contributions to the LP relaxation approach to weighted constraint satisfaction (= Gibbs energy minimization). We link this approach to many works from constraint programming, which relation has so ... -
Robust elastic 2D/3D geometric graph matching
(SPIE, 2012)We present an algorithm for geometric matching of graphs embedded in 2D or 3D space. It is applicable for registering any graph-like structures appearing in biomedical images, such as blood vessels, pulmonary bronchi, nerve ... -
Robust Non-Rigid Registration of 2D and 3D Graphs
(IEEE, 2012)We present a new approach to matching graphs embedded in R2 or R3. Unlike earlier methods, our approach does not rely on the similarity of local appearance features, does not require an initial alignment, can handle partial ... -
Selection of Speaker Independent Feature for a Speaker Verification System
(IEEE, 1998-08)In this paper we propose an optimisation technique to choose a user independent feature subset from the input feature set for a dynamic time-warping (DTW) based text-dependent speaker verification system. The results ... -
Spatio-Temporal Motion Estimation for Respiratory-Correlated Imaging of the Lungs
(American Association of Physicists in Medicine, 2011)Purpose: Four-dimensional computed tomography (4D CT) can provide patient-specific motion information for radiotherapy planning and delivery. Motion estimation in 4D CT is challenging due to the reduced image quality and ... -
Spatio-Temporal Nonrigid Registration for Ultrasound Cardiac Motion Estimation
(IEEE, 2005-09)We propose a new spatio-temporal elastic registration algorithm for motion reconstruction from a series of images. The specific application is to estimate displacement fields from two-dimensional ultrasound sequences of ... -
Stable affine frames on isophotes
(IEEE, 2007-10)We propose a new affine-covariant feature, the stable affine frame (SAF). SAFs lie on the boundary of extremal regions, i.e. on isophotes. Instead of requiring the whole isophote to be stable with respect to intensity ... -
The fast multipole method for the direct E/MEG problem
(IEEE, 2002)Reconstructing neuronal activity from MEG and EEG measurements requires the accurate calculation of the electromagnetic field inside the head. The boundary element formulation of this problem leads to a dense linear system ... -
The Multimodal Signature Method: An Efficiency and Sensitivity Study
(IEEE, 2000)The multimodal neighbourhood signature (MNS) method has given acceptable results both for the colour-based image retrieval and the object recognition task. Local colour content is concisely represented by invariant features ... -
Tracking by an Optimal Sequence of Linear Predictors
(IEEE, 2009-04)We propose a learning approach to tracking explicitly minimizing the computational complexity of the tracking process subject to user-defined probability of failure (loss-of-lock) and precision. The tracker is formed by a ... -
Tracking the Invisible: Learning Where the Object Might be
(IEEE, 2010-06)Objects are usually embedded into context. Visual context has been successfully used in object detection tasks, however, it is often ignored in object tracking. We propose a method to learn supporters which are, be it only ... -
Two-view Geometry Estimation Unaffected by a Dominant Plane
(IEEE, 2005-06)A RANSAC-based algorithm for robust estimation of epipolar geometry from point correspondences in the possible presence of a dominant scene plane is presented. The algorithm handles scenes with (i) all points in a single ... -
Unconstrained Licence Plate and Text Localization and Recognition
(IEEE, 2005-09)Licence plates and traffic signs detection and recognition have a number of different applications relevant for transportation systems, such as traffic monitoring, detection of stolen vehicles, driver navigation support ... -
Unified Framework for Semiring-Based Arc Consistency and Relaxation Labeling
(Verlag der Technischen Universität Graz, 2007-02)Constraint Satisfaction Problem (CSP), including its soft modifications, is ubiquitous in artificial intelligence and related fields. In computer vision and pattern recognition, the crisp CSP is more known as the consistent ... -
Unsupervised Discovery of Co-occurrence in Sparse High Dimensional Data
(IEEE, 2010-06)An efficient min-Hash based algorithm for discovery of dependencies in sparse high-dimensional data is presented. The dependencies are represented by sets of features co-occurring with high probability and are called ... -
Unwarping of Unidirectionally Distorted EPI Images
(IEEE, 2000-02)Echo-planar imaging (EPI) is a fast nuclear magnetic resonance imaging (MRI) method. Unfortunately, local magnetic field inhomogeneities induced mainly by the subject's presence cause significant geometrical distortion, ... -
Using gradient information to enhance the Progressive Probabilistic Hough Transform
(IEEE, 2000)In this paper we look at the benefits to be gained in using gradient information to enhance the progressive probabilistic Hough transform (PPHT). It is shown how using the angle information in controlling the voting process ... -
Using grammars for scene interpretation
(IEEE, 1996-09)A method that employs grammars to direct the inference process of a vision system that does interpretation of dynamic scenes is described. The system uses a set of qualitative image descriptors to drive the interpretation. ...
