Using cloud shadows to infer scene structure and camera calibration
We explore the use of clouds as a form of structured lighting to capture the 3D structure of outdoor scenes observed over time from a static camera. We derive two cues that relate ...

Dense Stereo Range Sensing with Marching Pseudo-Random Patterns
As an extension to classical structured lighting techniques, the use of bi-dimensional pseudo-random color codes is explored to perform range sensing with variable density from a ...

Analysis of Echoes in Single-Image Random-Dot-Stereograms
Three-dimensional depth information of a surface can be encoded in a two-dimensional image called single-image random-dotstereograms or, more widely known, autostereograms. It is ...
