The visual system of the flying insects is the source of inspiration for the presented hardware vision system. The faceted eyes of a common fly provide it with omnidirectional vision, egomotion and depth estimation. Utilizing the concept of faceted eyes, a ...
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 ...
The classic perspective projection is mostly used when calibrating a camera. Although this approach is fairly developed and often suitable, it is not necessarily adequate to model any camera system like fish-eyes or catadioptrics. The perspective projectio ...
A method for controlling the spectral response of light sensitive semiconductor elements in an array (8) using an electric control signal (Vop) applied to said semiconductor elements. The light sensitive semiconductor elements could be a single photon aval ...
This work tackles the challenge of detecting and matching objects in scenes observed simultaneously by fixed and mobile cameras. No calibration between the cameras is needed, and no training data is used. A fully automated system is presented to detect if ...
The objective of this thesis was to increase our understanding of gravity-driven geophysical flows by developing a new platform to simulate avalanches of fluid in the laboratory. To simulate flow avalanches in the laboratory, we created a unique experiment ...
A 3D imager is presented capable of computing the depth map as well as the intensity scale of a given scene. The heart of the system is a two-dimensional array of single photon avalanche diodes fabricated in standard CMOS technology. The diodes exhibit low ...
Remote detection by camera offers a versatile means for recording people activities. Relying principally on changes in video images, the method tends to fail in presence of shadows and illumination changes. This paper explores a possible remedy to these pr ...
Video cameras have been used in the graphic arts industry primarily for quality inspection applications where one is interested only in the macro or large scale appearance defects of the print i.e. acceptable/not acceptable. CCD video cameras also have the ...
In target tracking, fusing multi-modal sensor data under a power-performance trade-off is becoming increasingly important. Proper fusion of multiple modalities can help in achieving better tracking performance while decreasing the total power consumption. ...
