Cheap 3D Computer Vision? 102
InspectorPraline writes "According to this article at the New York Times [free reg req'd], a tech firm known as Tyzx is developing optics technology that will have three-dimensional capability -- using two cameras attached by a high-bandwidth connection to a custom processing card inside a PC. The article makes one believe that the system would have a top speed of as much as 132 stereo frames per second, which could be very useful in security systems. Of course, the real question is who's behind the cameras, but we can all drool over the other possibilities, right?"

<clip>
The DeepSea chip is hardware implementation of the census correspondence algorithm invented by Tyzx staff... The algorithm's key concept is transforming a pixel's numeric absolute intensity value into a bit string that represents the pixel's brightness relative ot it's neighboring pixels. For each pixel, The DeepSea chip examines the pixels surrounding area called a neighborhood. A typical neighborhood is 7x7 pixels centered on the subject pixel. Comparing a subject pixel's intensity to its neighbours, the chip produces a relative intensity map (show in the document, page 8).

The "Cyberscope" was quite cheap (Score:3, Informative)
Works with any software as it is attached at the front of the screen. Surface mirrors and the idea of doing the view-master 'on screen'
I'll keep mine for a long time.
