Visual Attention on the Sphere

Heinz Hügli, Iva Bogdanova Vandergheynst, Alexandre Bur

Human visual system makes an extensive use of visual attention in order to select the most relevant information and speed-up the vision process. Inspired by visual attention, several computer models have been developped and many computer vision application ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

The spherical approach to omnidirectional visual attention

Heinz Hügli, Iva Bogdanova Vandergheynst, Alexandre Bur

Computational visual attention (VA) has been widely investigated during the last three decades but the conventional algorithms are not suitable for omnidirectional images which often contain a significant amount of radial distortion. Only recently a comput ...

IP-LAB: A Tool to Teach Image Processing Programming in Java—Challenge in Swiss Federal Institute of Technology Lausanne

Michaël Unser, Daniel Sage

Image processing is getting more and more important because of the widespread use of digital imaging devices, such as digital cameras or digital videos. While image processing is a very practical discipline, it is perceived as being rather theoretical. It ...

Matrix-based analysis of digital images: application to goniophotometric measurements with variable referential

Marilyne Andersen

Digital video-based luminance mapping systems require the establishment of a precise relation between the considered spatial referential and the associated pixel coordinates on the image. Such a relation may vary with the measurement conditions, and an adj ...

Experimental and simulation-based approaches to assess bidirectional properties of complex fenestration systems

Marilyne Andersen

A serious effort has been made in developing accurate and efficient bidirectional goniophotometric devices for detailed studies of Complex Fenestration Systems, capable of measuring BTDFs and/or BRDFs in an appropriate way. The existing instruments are alm ...

Virtual Sensor Design

Sabine Süsstrunk, Roberto Costantini

We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...

Automated cartographic annotation of digital images

Martin Vetterli, Serge Ayer

For annotating a digital image with information from a digital map, features which are visible from a viewer position are extracted from the map. The extracted features are matched with corresponding features in the image, and feature annotations are trans ...
