Methods of trajectory estimation in challenging mapping scenarios
With the aim of improving trajectory estimation and point cloud georeferencing in the scope of Kinematic Laser Scanning (ALS), we recently proposed a novel procedure leveraging the automated extraction of reliable 3D point to point correspondences and thei ...
2023Tracking Adaptation to Improve SuperPoint for 3D Reconstruction in Endoscopy
Endoscopy is the gold standard procedure for early detection and treatment of numerous diseases. Obtaining 3D reconstructions from real endoscopic videos would facilitate the development of assistive tools for practitioners, but it is a challenging problem ...
Springer2023Neural Parts: Learning Expressive 3D Shape Abstractions with Invertible Neural Networks
Angelos Katharopoulos, Andreas Geiger, Despoina Paschalidou
Impressive progress in 3D shape extraction led to representations that can capture object geometries with high fidelity. In parallel, primitive-based methods seek to represent objects as semantically consistent part arrangements. However, due to the simpli ...
IEEE COMPUTER SOC2021Nanoscale Pattern Extraction from Relative Positions of Sparse 3D Localizations
Suliana Manley, Christian Sieben
Inferring the organization of fluorescently labeled nanosized structures from single molecule localization microscopy (SMLM) data, typically obscured by stochastic noise and background, remains challenging. To overcome this, we developed a method to extrac ...
AMER CHEMICAL SOC2021Fusion of Photo with Airborne Laser Scanning
Jan Skaloud, Emmanuel Pierre Quentin Clédat
Photogrammetry and Laser-Scanning are usually considered as complementary. Integration of these two observation methods has the potential to blend their individual advantages. The resulting benefit is likely to be higher in drone airborne mapping, which pa ...
2020On the adjustment, calibration and orientation of drone photogrammetry and laser-scanning
Emmanuel Pierre Quentin Clédat
Centimetre level precision mapping is essential for many applications such as land-use, infrastructure inspection, cultural heritage preservation, and construction site monitoring. However, the acquisition and its preparation (in particular the setting of ...
EPFL2020Deformation-aware Unpaired Image Translation for Pose Estimation on Laboratory Animals
Pascal Fua, Pavan P Ramdya, Helge Jochen Rhodin, Semih Günel, Siyuan Li, Mirela Ostrek
Our goal is to capture the pose of neuroscience model organisms, without using any manual supervision, to be able to study how neural circuits orchestrate behaviour. Human pose estimation attains remarkable accuracy when trained on real or simulated datase ...
2020C-blox: A Scalable and Consistent TSDF-based Dense Mapping Approach
In many applications, maintaining a consistent dense map of the environment is key to enabling robotic platforms to perform higher level decision making. Several works have addressed the challenge of creating precise dense 3D maps from visual sensors provi ...
2019Learning Monocular 3D Human Pose Estimation from Multi-view Images
Pascal Fua, Mathieu Salzmann, Frédéric Meyer, Isinsu Katircioglu, Helge Jochen Rhodin, Victor Constantin
Accurate 3D human pose estimation from single images is possible with sophisticated deep-net architectures that have been trained on very large datasets. However, this still leaves open the problem of capturing motions for which no such database exists. Ma ...
