Information-Theoretic Registration with Explicit Reorientation of Diffusion-Weighted Images

1 code implementation28 May 2019 Henrik Grønholt Jensen, François Lauze, Sune Darkner

We present an information-theoretic approach to the registration of images with directional information, and especially for diffusion-Weighted Images (DWI), with explicit optimization over the directional scale.

Scale-Regularized Filter Learning

no code implementations10 Jul 2017 Marco Loog, François Lauze

We start out by demonstrating that an elementary learning task, corresponding to the training of a single linear neuron in a convolutional neural network, can be solved for feature spaces of very high dimensionality.

LED-based Photometric Stereo: Modeling, Calibration and Numerical Solution

no code implementations4 Jul 2017 Yvain Quéau, Bastien Durix, Tao Wu, Daniel Cremers, François Lauze, Jean-Denis Durou

The second one directly recovers the depth, by formulating photometric stereo as a system of PDEs which are partially linearized using image ratios.

Optimization over Geodesics for Exact Principal Geodesic Analysis

1 code implementation11 Aug 2010 Stefan Sommer, François Lauze, Mads Nielsen

In fields ranging from computer vision to signal processing and statistics, increasing computational power allows a move from classical linear models to models that incorporate non-linear phenomena.
