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 ...

Revisiting Radiometric Calibration for Color Computer Vision

Sabine Süsstrunk, Seungryong Kim, Matthew Brown

We present a study of radiometric calibration and the in-camera imaging process through an extensive analysis of more than 10,000 images from over 30 cameras. The goal is to investigate if image values can be transformed to physically meaningful values and ...

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 ...

Motion Parallax Based Restitution of 3D Images on Legacy Consumer Mobile Devices

Touradj Ebrahimi, Martin Rerabek, Jong Seok Lee, Lutz Goldmann

While 3D display technologies are already widely available for cinema and home or corporate use, only a few portable devices currently feature 3D display capabilities. Moreover, the large majority of 3D display solutions rely on binocular perception. In th ...

GPU-accelerated Convex Multi-phase Image Segmentation

Jean-Philippe Thiran, Xavier Bresson, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Hadrien Copponnex, Arnaud Le Carvennec

Image segmentation is a key area of research in computer vision. Recent advances facilitated reformulation of the non-convex multi-phase segmentation problem as a convex optimization problem (see for example [2, 4, 9, 10, 13, 16]). Recently, [3] proposed a ...

Results of the prototype camera for FACT

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomulti ...
