Barents Lessons: Teaching and Research in Architecture

Barents Lessons presents the results of a research project in the remote, yet resource-rich and for this reason geo-strategically crucial Barents Sea region. Starting with the thesis that the ocean is an urbanized territory, master students at laba (Labora ...

Three-dimensional scanning microscopy through thin turbid media

Demetri Psaltis, Ye Pu, Chia-Lung Hsieh, Xin Yang

We demonstrate three-dimensional imaging through a thin turbid medium using digital phase conjugation of the second harmonic signal emitted from a beacon nanoparticle. The digitally phase-conjugated focus scans the volume in the vicinity of its initial pos ...

The Gigavision Camera: A 2Mpixel Image Sensor with 0.56um2 1-T Digital Pixels

Edoardo Charbon, Hyungjune Yoon

We present a CMOS image sensor with deep-subwavelength, digital 1-T pixels designed for use in a digital film concept known as Gigavision (GV) camera. In GV, the levels of gray in the picture are derived from the concentration of activated pixels. Activate ...

Resolution-Invariant Separable Arma Modeling Of Images

Michaël Unser, Aurélien Bourquard, Hagay Kirshner

We suggest a continuous-domain stochastic modeling of images that is invariant to spatial resolution. Specifically, we are proposing an estimator that is calibrated with respect to the sampling step, and that can potentially handle aliased data. Motivated ...

Parts-Based Face Verification using Local Frequency Bands

Sébastien Marcel

In this paper we extend the Parts-Based approach of face verification by performing a frequency-based decomposition. The Parts-Based approach divides the face into a set of blocks which are then considered to be separate observations, this is a spatial dec ...

Subpixel translation of MEMS measured by discrete Fourier transform analysis of CCD images

Martinus Gijs, Christophe Yamahata, Marc Stranczl

We present a straightforward method for measuring in-plane linear displacements of microelectromechanical systems (MEMS) with a subnanometer resolution. The technique is based on Fourier transform analysis of a video recorded with a Charge-Coupled Device ( ...

Imaging based interferometric pressure sensor

Demetri Psaltis, Wuzhou Song

An imaging based interferometric pressure sensor apparatus compromise a fluid pressure sensor unit (1) and an optical monitor (2). The disposable pressure sensor part comprises a rigid transparent cover plate 3 and a flexible diaphragm (4), in between form ...

A Switched Capacitor Fully Differential Correlated Double Sampling Circuit for CMOS Image Sensors

Sandro Carrara, Yusuf Leblebici, Gözen Köklü

Complementary metal oxide semiconductor (CMOS) image sensors are more compatible than charge coupled devices (CCDs) for lab-on-a-chip platforms due to their inherited advantages. However, without the noise reduction circuits, CMOS technology wouldn’t be ab ...

Segment-Based Real-Time Stereo Vision Matching using Characteristics Vectors

Jean-Philippe Thiran

Stereo vision is a usual method to obtain depth information from images. The problems encountered when applying well established algorithms to real-time applications are due to the high computational load required. In this article we address this issue by ...
