Efficient Scanning for EM Based Target Localization

Pascal Fua, Graham Knott, Raphael Sznitman, Aurélien Lucchi, Natasa Pjescic-Emedi

For biologists studying the morphology of cells, Electron Microscopy (EM) is the method of choice with its {\it nm} resolution, across increasingly larger volumes. However, the time necessary to acquire such image series is long and often limits the amount ...

Selected Contributions on Multimedia Quality Evaluation

Francesca De Simone

Multimedia signals, such as digital images and video sequences, are captured, processed and finally presented to human observers who directly or indirectly judge their quality. During the data acquisition, as well as the many steps of the processing chain, ...

Gradient Response Maps for Real-Time Detection of Textureless Objects

Pascal Fua, Vincent Lepetit, Slobodan Ilic

We present a method for real-time 3D object instance detection that does not require a time-consuming training stage, and can handle untextured objects. At its core, our approach is a novel image representation for template matching designed to be robust t ...

Merging of image data in electron crystallography

Henning Paul-Julius Stahlberg

Electron crystallography of membrane proteins uses cryo-transmission electron microscopy to record images and diffraction patterns of frozen-hydrated 2D crystals. Each two-dimensional (2D) crystal is only imaged once, at one specific tilt angle, and the re ...

Multipactor saturation in parallel-plate waveguides

Michael Mattes, Francisco Edén Sorolla Rosario

The saturation stage of a multipactor discharge is considered of interest, since it can guide towards a criterion to assess the multipactor onset. The electron cloud under multipactor regime within a parallel-plate waveguide is modeled by a thin continuous ...

An Efficient Demosaicing Technique using Geometrical Information

Sabine Süsstrunk

Color image sensors use color filter arrays (CFA) to capture information at each sensor pixel position and require color demosaicing to reconstruct full color images. The quality of the demosaicked image is hindered by the sensor characteristics during the ...

Digital confocal microscope

Demetri Psaltis, Alexandre Goy

We demonstrate experimentally a scanning confocal microscopy technique based on digital holography. The method relies on digital holographic recording of the scanned spot. The data collected in this way contains all the necessary information to digitally p ...

Simulated biological cells for receptor counting in fluorescence imaging

Giovanni De Micheli, Sandro Carrara, Julien Michel Ghaye

Digital image processing and epi-fluorescence microscopy provide one of the main and basic tools for living biological cells analysis and studying. Developing, testing and comparing those image processing methods properly require the use of a controlled en ...

Experimental Analysis of Lag Sources in Pinned Photodiodes

Maher Kayal, Nicolas Blanc, Lysandre-Edouard Bonjour

A measurement method is reported to distinguish the different mechanisms that lead to image lag in image sensors based on pinned photodiodes (PPDs). This new method can differentiate between the lag caused by a potential barrier or pocket and gate traps in ...

Bits from Photons

Feng Yang

The trends in the design of image sensors are to build sensors with low noise, high sensitivity, high dynamic range, and small pixel size. How can we benefit from pixels with small size and high sensitivity? In this dissertation, we study a new image senso ...
