Tracking and Rendering Using Dynamic Textures on Geometric Structure from Motion
Estimating geometric structure from uncalibrated images accurately enough for high quality rendering is difficult. We present a method where only coarse geometric structure is tracked and estimated from a moving camera. Instead a precise model of the intensity image variation is obtained by overlaying a dynamic, time varying texture on the structure. This captures small scale variations (e.g. non-planarity of the rendered surfaces, small camera geometry distortions and tracking errors). The dynamic texture is estimated and coded much like in movie compression, but parameterized in 6D pose instead of time, hence allowing the interpolation and extrapolation of new poses in the rendering and animation phase. We show experiments tracking and re-animating natural scenes as well as evaluating the geometric and image intensity accuracy on constructed special test scenes. A problem of significant interest is how to capture and represent the image information from several sample views of a scen...
