There is some interesting computational photography news from this year’s Siggraph from Microsoft Research with the University of Washington, Seattle and the University of California, Berkeley. Firstly Finding Paths through the World’s Photos is an update on last year’s Photosynth. It uses a set of images to recreate an environment from the cameras they were shot through. You can then move through that environment, through the most approriate images. This includes stabilisation and colour matching. Also Unwrap Mosaics is a method of texture mapping video footage directly without 3d geometry. It can also be used to track in other 2d layers. And finally Using Photographs to Enhance Videos of a Static Scene uses the parallax information to generate depth information from video footage. This is used to blend a set of photographs of the same scene to enhance the resolution and dynamic range of the footage. Hopefully this technology will be commercialised soon!
