The 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 Portfolio2024Validation of 2D T e and n e measurements made with Helium imaging spectroscopy in the volume of the TCV divertor
Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Artur Perek, Sophie Danielle Angelica Gorno, Claudia Colandrea, Dmytry Mykytchuk, Cedric Kar-Wai Tsui, Hugo De Oliveira, Filippo Bagnato, Lorenzo Martinelli, Nicola Offeddu
Multi-spectral imaging of helium atomic emission (HeMSI) has been used to create 2D poloidal maps of T-e and ne in TCV's divertor. To achieve these measurements, TCV's MANTIS multispectral cameras (Perek et al 2019 Rev. Sci. Instrum. 90 123514) simultaneou ...
2023Importance of 3D radiative transfer effects on high-resolution NO2 remote sensing in cities
Urban air quality is a major concern in the context of human health since cities are at the same time emission hot spots and home to a large fraction of the world's population. Airborne imaging spectrometers may be a valuable addition to traditional air po ...
EPFL2022Imaging-based spectrometer-less optofluidic biosensors based on dielectric metasurfaces for detecting extracellular vesicles
Hatice Altug, Michele De Palma, Filiz Yesilköy, Chiara Cianciaruso, Yasaman Jahani, Eduardo Romero Arvelo
Biosensors are indispensable tools for public, global, and personalized healthcare as they provide tests that can be used from early disease detection and treatment monitoring to preventing pandemics. We introduce single-wavelength imaging biosensors capab ...
2021Thermally-Drawn Multi-Electrode Fibers for Bipolar Electrochemistry and Magnified Electrochemical Imaging
Imaging systems using closed bipolar electrode (cBPE) arrays and electrochemiluminescence (ECL) have attracted great attention in recent years as a 2D imaging platform with high spatiotemporal resolution. However, the fabrication techniques for cBPE arrays ...
WILEY2021Geometry-Aware Deep Recurrent Neural Networks for Hyperspectral Image Classification
Mathieu Salzmann, Wei Wang, Siyuan Hao
Variants of deep networks have been widely used for hyperspectral image (HSI)-classification tasks. Among them, in recent years, recurrent neural networks (RNNs) have attracted considerable attention in the remote sensing community. However, complex geomet ...

Hatice Altug, Andreas Tittl, Aleksandrs Leitis
Low-loss nanostructured dielectric metasurfaces have emerged as a breakthrough platform for ultrathin optics and cutting-edge photonic applications, including beam shaping, focusing, and holography. However, the static nature of their constituent materials ...
WILEY-V C H VERLAG GMBH2020Homogeneous multifocal excitation for high-throughput super-resolution imaging
Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Khalid Ashraf Mohie Ibrahim, Davide Gambarotto, Paul Guichard, Virginie Hamel, Denis Fortun, Niccolo Banterle, Dora Mahecic
Super-resolution microscopies have become an established tool in biological research. However, imaging throughput remains a main bottleneck in acquiring large datasets required for quantitative biology. Here we describe multifocal flat illumination for fie ...
NATURE PUBLISHING GROUP2020Active illumination and computational Methods for Temporal and Spectral Super-Resolution Microscopy
Light microscopy is a tool of paramount importance for biologists and has been constantly improved for the past four centuries. Despite many recent developments, microscopy techniques still require improvement, especially to reach better temporal and spect ...
EPFL2020Development of a real-time algorithm for detection of the divertor detachment radiation front using multi-spectral imaging
Christian Gabriel Theiler, Artur Perek, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers
In this paper we present a novel algorithm to extract the optical plasma boundary and radiation front for detached divertor plasmas. We show that reliable detection of the divertor leg and radiation front is possible using lightweight image processing tool ...
