Fast Registration by Boundary Sampling and Linear Programming
We address the problem of image registration when speed is more important than accuracy. We present a series of simplification and approximations applicable to almost any pixel-based image similarity criterion...

Detection and Localization of Drosophila Egg Chambers in Microscopy Images
Drosophila melanogaster is a well-known model organism that can be used for studying oogenesis (egg chamber development) including gene expression patterns. Standard analysis methods require manual segme...

Binary Pattern Dictionary Learning for Gene Expression Representation in Drosophila Imaginal Discs
We present an image processing pipeline which accepts a large number of images, containing spatial expression information for thousands of genes in Drosophila imaginal discs. We assume that the gene activation...

Langerhans Islet Volume Estimation from 3D Optical Projection Tomography
This paper concerns the comparison of automatic volume estimation methods for isolated pancreatic islets. The estimated islet volumes are needed during the process of assessing the islet sample quality prior t...

Path Descriptors for Geometric Graph Matching and Registration
Graph and tree-like structures such as blood vessels and neuronal networks are abundant in medical imaging. We present a method to calculate path descriptors in geometrical graphs, so that the similarity betwe...

Active Testing Search for Point Cloud Matching
We present a general approach for solving the point-cloud matching problem for the case of mildly nonlinear transformations. Our method quickly finds a coarse approximation of the solution by exploring a reduc...

Respiratory Motion Estimation from Cone-Beam Projections Using a Prior Model
Respiratory motion introduces uncertainties when planning and delivering radiotherapy for lung cancer patients. Cone-beam projections acquired in the treatment room could provide valuable information for build...

High-Dimensional Entropy Estimation for Finite Accuracy Data: R-NN Entropy Estimator
We address the problem of entropy estimation for high-dimensional finite-accuracy data. Our main application is evaluating high-order mutual information image similarity criteria for multimodal image registrat...

Image Registration Accuracy Estimation Without Ground Truth Using Bootstrap
We consider the problem of estimating the local accuracy of image registration when no ground truth data is available. The technique is based on a statistical resampling technique called bootstrap. Only the tw...

Consistent and Elastic Registration of Histological Sections Using Vector-Spline Regularization
Here we present a new image registration algorithm for the alignment of histological sections that combines the ideas of B-spline based elastic registration and consistent image registration, to allow simultan...

Computational Elastography from Standard Ultrasound Image Sequences by Global Trust Region Optimization
A new approach is proposed to estimate the spatial distribution of shear modulus of tissues in-vivo. An image sequence is acquired using a standard medical ultrasound scanner while varying the force applied to...

Symmetric BEM Formulation for the M/EEG Forward Problem
The forward M/EEG problem consists in simulating the electric potential and the magnetic field produced outside the head by currents in the brain related to neural activity. All previously proposed solutions u...
