Fast and robust single particle reconstruction in 3D fluorescence microscopy

no code implementations23 Jan 2023 Thibaut Eloy, Etienne Baudrier, Marine Laporte, Virginie Hamel, Paul Guichard, Denis Fortun

Single particle reconstruction has recently emerged in 3D fluorescence microscopy as a powerful technique to improve the axial resolution and the degree of fluorescent labeling.

Multiview point cloud registration with anisotropic and space-varying localization noise

no code implementations3 Jan 2022 Denis Fortun, Etienne Baudrier, Fabian Zwettler, Markus Sauer, Sylvain Faisan

Our approach follows the widely used framework of Gaussian mixture model (GMM) reconstruction with an expectation-maximization (EM) algorithm.

Fast Piecewise-Affine Motion Estimation Without Segmentation

no code implementations6 Feb 2018 Denis Fortun, Martin Storath, Dennis Rickert, Andreas Weinmann, Michael Unser

Current algorithmic approaches for piecewise affine motion estimation are based on alternating motion segmentation and estimation.

Aggregation of local parametric candidates with exemplar-based occlusion handling for optical flow

no code implementations22 Jul 2014 Denis Fortun, Patrick Bouthemy, Charles Kervrann

The idea is to supply local motion candidates at every pixel in a first step, and then to combine them to determine the global optical flow field in a second step.
