]]> Video manipulation is becoming the next big thing online. Techniques that were once limited to high end commercial studios are coming out as web based services, services that have huge potential for data communication and visualisation.

Take a look at the latest service from Standard University below, known as ZunaVision:

Note how the shadows fall on the walls as well as the video, if you have a video you would like a try the simple go to http://zunavision.stanford.edu/ to try it out.

]]> Video tracking has huge potential for communicating issues of place and space in the urban environment as well as for data tagging and data collection for use in a GIS. Last weeks post on tracking pedestrians highlighted what could be archived with a simple webcam, if you add in computer vision and on the fly path analysis then you take the concept a step further.

Three dimensional video tracking has been around for a while but it is generally restricted to high end packages. If you have ever wanted to tag data onto video objects, analyse traffic flows and pedestrian paths or augment scenes then the video below brings it a step closer to consumer level:
