A Real-time Inertial Motion Blur Metric: Application to Frame Triggering Based Motion Blur Minimization
Mobile robots suffer from sensory data corruption due to body oscillations and disturbances. In particular, information loss on images captured with onboard cameras can be very high, and such loss may become irreversible or computationally costly to undo. ...

IEEE2014Further study on iterative control loop for aberration correction in imaging systems with single mode fibre aperture
An iterative control system was designed for compensation of wavefront aberration utilizing a micromachined deformable mirror through simulated annealing algorithm. 37 elements within a deformable mirror are controlled individually in a closed-loop to maxi ...
Natl Inst Optoelectronics2013Multiple-Field Approach for Aberration Correction in Miniature Imaging Systems Based on Wafer-Level Production
Hans Peter Herzig, Toralf Scharf, Nicolas Bongard
IIn mobile imaging systems, the most difficult element to integrate is the objective lens. Here we present an intermediate approach between the costly traditional objectives and the low-resolution objectives inspired by the compound eyes of insects. Our mu ...
SPIE Digital Library2013Curved Transflective Holographic Screens for Head-Mounted Display
Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher, Arnaud Mader, Seyedpayam Vahdati
A volume hologram recorded with a lens array is proposed as a transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a projection system, with similar properties to one mounted on ...
Spie-Int Soc Optical Engineering2013Miniature curved artificial compound eyes
Dario Floreano, Ramon Pericet Camara, Michal Karol Dobrzynski, Géraud L'Eplattenier
In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, and high temporal resolution in a tiny ...
National Academy of Sciences2013Joint Statistical Analysis of Images and Keywords with Applications in Semantic Image Enhancement
Sabine Süsstrunk, Albrecht Johannes Lindner, Appu Shaji
With the advent of social image-sharing communities, millions of images with associated semantic tags are now available online for free and allow us to exploit this abundant data in new ways. We present a fast non-parametric statistical framework designed ...
2012A Psf-Based Approach To Biplane Calibration In 3D Super-Resolution Microscopy
Michaël Unser, Suliana Manley, Daniel Sage, Hagay Kirshner, Thomas Pengo
Super-resolution localization microscopy methods such as PALM and STORM have been shown to provide imaging with resolutions up to a few tens of nanometers while using relatively simple setups. Biplane PALM has extended the PALM technique to three-dimension ...

IEEE2012Assessing the benefits of focal pair cryo-electron tomography
Cryo electron tomography provides nanometer-scale information on biological matter preserved in a close-to native state. The resolution of tomograms and structures resolved by sub-tomogram averaging is typically limited by the contrast transfer function of ...
