Image-based rendering of range data with estimated depth uncertainty

When rendering images from photographs, acquiring and registering data is a challenge. A solution to this problem is provided by an image-rendering approach that involves three steps. First, a depth map is computed for every input image. Second, the uncertainty information is calculated using the estimated depth maps as starting points. Finally, actual rendering, which renders the uncertainty estimated in the previous step as ellipsoidal Gaussian plots, is performed.
