IScan3D

This application for Iphone send photo content to a server that compute dense 3D point cloud and triangulate it and texture it. For sure they do not speak about precision of the output and if we could manage to have a metric reconstruction and they do not speak about the time to upload content to the server (i.e. image content that could be huge)!

It's hardly probable that they used already known product like :
Bundler/PMVS2 and home algorithm.

You could manage do the "the same" by running on a server a toolkit like the following :

What Android Is ?

You want information about the Android SDk:

Take a look to the following link (It will show you with slides the principal component) :

Kinect How they guess the depth : IR projection

With the desire to understand how Kinect detect the depth I have found this movie that show the IR projections.
You could see a series of dots ! They project dots of different size. So they have to solve the deformation that the IR camera see by knowing the projected IR patterns (Kind of StructuredLight system).

London 80 giga pixel panorama

The old record of 70 giga pixel (Budapest) is now over :

London : This is an 80-gigapixel panoramic photo, made from 7886 individual images. This panorama was shot from the top of the Centre Point building in central London, in the summer of 2010. We hope that the varied sights and energy of London have been captured here in a way never done before, so that you can experience one of the world's great cities - wherever you may be right now.

For the hardware they used :
We would like to thank Fujitsu Technology Solutions for providing the great hardware we used to help to make this image. This panoramic photo was stitched on a Fujitsu CELSIUS workstation comprising dual 6-core CPUs, 192GB of RAM, and a 4GB graphics card. Using this excellent workstation allowed this record-breaking photo to be created a few weeks faster than would have been possible on any other available PC. You can read more about our great experience using the CELSIUS workstation on Fujitsu's blog.

Intel OpenCL SDK

Intel® OpenCL* SDK is an Alpha software release. It is an implementation of the OpenCL* 1.1 standard optimized for Intel® Core^TMprocessors, running on Microsoft* Windows* 7 and Windows Vista* operating systems.

This Alpha software brings OpenCL* for the CPU in support of OpenCL developers desiring CPU advantages found on many OpenCL*workloads. OpenCL* language and Application Programming Interface (API) enables you to seamlessly take advantage of the Intel® Core^TM processor benefits such as Intel® Streaming SIMD Extensions (Intel® SSE) utilization and Multi-Core scalability.

The SDK comes with four samples including two graphics related demos: GodRays andMedianFilter
