Imaging sensor device using an array of single-photon avalanche diode photodetectors
Edoardo Charbon, Andrei Ardelean
The invention relates to an Imaging sensor device in a stacked arrangement comprising: - a pixel array tier comprising a plurality of pixel segments each having a plurality of pixels for photon detection each providing a digital pixel output; - a processin ...
2024The multimodality cell segmentation challenge: toward universal solutions
Sahand Jamal Rahi, Vojislav Gligorovski, Marco Labagnara, Jun Ma, Xin Yang, Maxime Emmanuel Scheder, Yao Zhang, Bo Wang, Yixin Wang, Lin Han
Cell segmentation is a critical step for quantitative single-cell analysis in microscopy images. Existing cell segmentation methods are often tailored to specific modalities or require manual interventions to specify hyper-parameters in different experimen ...
Nature Portfolio2024Burst Vision Using Single-Photon Cameras
Edoardo Charbon, Paul Mos, Mohit Gupta
Single-photon avalanche diodes (SPADs) are novel image sensors that record the arrival of individual photons at extremely high temporal resolution. In the past, they were only available as single pixels or small-format arrays, for various active imaging ap ...
IEEE COMPUTER SOC2023Learning rich optical embeddings for privacy-preserving lensless image classification
Martin Vetterli, Eric Bezzam, Matthieu Martin Jean-André Simeoni
By replacing the lens with a thin optical element, lensless imaging enables new applications and solutions beyond those supported by traditional camera design and post-processing, e.g. compact and lightweight form factors and visual privacy. The latter ari ...
2022augmented-stacking
Katrin Beyer, Yves Weinand, Julien Gamerro, Andrea Settimi, Qianqing Wang, David Rebiffe
Augmented Stacking is an augmented system designed to guide inexperienced users through the stacking of complex and irregular geometries. This digital fabrication system was applied to the assembly of one layer of a half-timber dry-stone wall. Augmented St ...
2022System and methods for differential imaging using a lock-in camera
Christophe Moser, Timothé Laforest, Damien Claude-Marie Loterie, Chiara Bonati
The present invention describes an imaging system that allows visualization of a wide range of samples both in terms of morphology and in terms of material (e.g. density distribution, varying chemical composition, or anything that induces a change of optic ...
2021Simulated Half-Fourier Acquisitions Single-shot Turbo Spin Echo (HASTE) of the Fetal Brain: Application to Super-Resolution Reconstruction
Meritxell Bach Cuadra, Tobias Kober, Tom Hilbert, Thomas Yu, Sébastien Tourbier, Reto Meuli, Patric Hagmann, Hamza Kebiri
Accurate characterization of in utero human brain maturation is critical as it involves complex interconnected structural and functional processes that may influence health later in life. Magnetic resonance imaging is a powerful tool complementary to the u ...
SPRINGER INTERNATIONAL PUBLISHING AG2021Differentiable inverse rendering based on radiative backpropagation
Wenzel Alban Jakob, Merlin Eléazar Nimier-David
A computer-implemented inverse rendering method is provided. The method comprises: computing an adjoint image by differentiating an objective function that evaluates the quality of a rendered image, image elements of the adjoint image encoding the sensitiv ...
2021NTIRE 2021 Depth Guided Image Relighting Challenge
Sabine Süsstrunk, Majed El Helou, Ruofan Zhou, Radu Timofte
Image relighting is attracting increasing interest due to its various applications. From a research perspective, image relighting can be exploited to conduct both image normalization for domain adaptation, and also for data augmentation. It also has multip ...
2021Beyond Cameras: Real-Time High-Resolution 3D and Panoramic MultiView Vision Systems with Their Applications
The cameras are invented by imitating the human visual system to capture the scene. The camera
technologies have been substantially advanced in recent years. 108 MP resolution with 100x hybrid
zoom has become standard features for smartphone flagships. In ...
