You have an openCV link on your demo page. Disregard my previous comment. Google, Microsoft and others are expanding their use of machine learning algorithms applied to the computer vision domain. They use segmentation to break the image into pieces and then use Bayesian inference for recognition. Prof Fei Fei Li's presentations on machine learning applied to computer vision. http://people.csail.mit.edu/torralba/shortCourseRLOC/index.html http://videolectures.net/mlas06_li_gmvoo/ Look at the web service http://www.iqengines.com/ You have 1000 free queries to play with. You can even submit your own training data. Whoops. You have an openCV link on your demo page. Disregard my previous comment.

There are also Python libraries for interfacing to openCV and Nvidia CUDA acceleration for some of openCV. http://opencv.willowgarage.com/wiki/ http://pointclouds.org/ You are probably aware of Willow Garage’s support of openCV ( computer vision ) and PCL ( point cloud libraries ) in C++.

But I'm not Microsoft nor Google! This is why I really hope that Microsoft is working in that direction with Read/Write World... The pose is computed using <a href="http://www.visual-experiments.com/2011/05/09/news-about-opensynther/" rel="nofollow">OpenSynther</a>: I'm not using the photosynth point cloud, only cameras positions to compute my own Sift-based point cloud. Then I'm estimating the pose with a ransac epnp solution using 2d/3d correspondences.

How do you estimete the right pose? I believe that you have only pointcloud downloaded from photosynth and you need to find relation between photo and the pointcloud, or do you have something else?
