The above pictures show two applications for enhance reality visualization. The image on the left shows a three dimensional model with two virtual windows . The virtual windows are attached to the model and as the camera's view point changes they are displayed with proper perspective. Click on the left image to see an mpeg movie of moving virtual windows. The image on the left shows video of a skull registered with CT data for the same skull. A new formulation of the camera calibration problem enables us to efficiently create enhance reality visualizations using only a single image from an uncalibrated camera.
