Practical computational imaging by use of spatiotemporal light modulation: from simulations to applications in biological microscopy
Optical microscopy is an essential tool for biologists, who are often faced with the need to overcome the spatial and temporal resolution limitations of their devices to capture finer details. As upgrading imaging hardware is expensive, computational metho ...
EPFL2023Development of novel experimental and computational methods for three-dimensional coherent and super-resolution microscopy
Adrien Charles-François Raymond Descloux
Optical microscopy is one widely used tool to study cell functions and the interaction of molecules at a sub-cellular level. Optical microscopy techniques can be broadly divided into two categories: partially coherent and incoherent. Coherent microscopy te ...
EPFL2020HISTOBREAST, a collection of brightfield microscopy images of Haematoxylin and Eosin stained breast tissue
Modern histopathology workflows rely on the digitization of histology slides. The quality of the resulting digital representations, in the form of histology slide image mosaics, depends on various specific acquisition conditions and on the image processing ...
2020Spatially-Variant CNN-Based Point Spread Function Estimation for Blind Deconvolution and Depth Estimation in Optical Microscopy
Michael Stefan Daniel Liebling, Adrian Shajkofci
Optical microscopy is an essential tool in biology and medicine. Imaging thin, yet non-flat objects in a single shot (without relying on more sophisticated sectioning setups) remains challenging as the shallow depth of field that comes with high-resolution ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Graph-based regularization of inverse problems in imaging
As of today, the extension of the human visual capabilities to machines remains both a cornerstone and an open challenge in the attempt to develop intelligent systems. On the one hand, the development of more and more sophisticated imaging devices, capable ...
EPFL2020High-resolution interference microscopy of binary phase diffractive optical elements
Toralf Scharf, Dong Cheon Kim, Michail Symeonidis
In this work, we apply the high-resolution interference microscopy technique to investigate the intensity and phase of light transmitted through a binary phase element. Using a combination of simulation and experimental results, we identify specific featur ...
OPTICAL SOC AMER2019Software Tools for Handling Magnetically Collected Ultra-thin Sections for Microscopy
This report presents the software tools that will be available online to help users accurately segment ultra-thin sections of brain tissue in a large image to determine the section’s coordinates. In order to predict these coordinates, the goal was to use a ...
2019Compact lensless digital holography
Microscopy is of high interest for biology since it allows imaging features that are too small to
be seen with naked eyes. However, cells are mostly transparent to visible and infrared light
which makes it difficult to see with a traditional microscope. To ...
EPFL2018Dielectric-sphere-based microsystem for optical super-resolution imaging
Well-established imaging techniques proved that features below the diffraction limit can be observed optically using so-called super-resolution microscopies, which overcome Abbe's resolution limit. In traditional far-field microscopy, the introduction of f ...
EPFL2018Coherent imaging from bacteria to multicellular organisms
Structural and functional imaging of cells, tissues and organisms is crucial for understanding biomedical processes. Fluorescence microscopy is an established tool and has contributed to many discoveries in the life sciences. This technique provides molecu ...
