All Silicon Graphics computers have been substituted by PCs, the Origin 200 server by a dual Intel Xeon (total 8 cores for OpenMP), with various Nvidia graphics (Tesla etc.) for CUDA programming.
The Olympus BX40 microscope with Polaroid Digital Microscope Camera (max 1200x1600 in 24 bit color) and Physik Instrumente P-721.10 piezotranslator (max 90 microns; 10nm steps) is waiting for a student expert in optics and inverse ray-tracing, to tackle 3D reconstruction of transparent objects like diatom valves.
The Cambridge VSG2/3F Visual Stimulus Generator with OptiCal has been donated to Alexandra Reis from Psychology.

Links and affiliations

An absolute must is to visit the Computer Vision Home Page and the Vision Science webpages, where you can find almost all (?) our colleagues in the world working on computer and/or human vision. Another useful site with lots of information is CVonline. You can also take a look at Wavelets for Texture Analysis, Wavelets Internet Sources, and last but not least the Gabor Digest as well as the Wavelet Digest.
If you are interested in neuroscience, including visual psychophysics, the modeling of visual perception, as well as neurophysiology of cortical processing, you can use a very powerful search engine at the Neuroscience Web Search site.
For discussions, FAQs, etc, see the newsgroups sci.image.processing and comp.ai.vision. Another useful source of information is Adrian Clark's PIXEL.


The Vision Laboratory is affiliated with the ISR Signal Processing Lab at the Tecnico in Lisbon and the Portuguese Association for Pattern Recognition APRP.
