We introduce a novel framework for efficient stereo disparity estimation leveraging the spatial smoothness typically assumed in stereo and formalized by the various smoothness constraints. The smoothness constraint presumes that a neighboring set of pixels shares the same disparity or the disparity varies smoothly. Our key insight is that it hence suffices to evaluate any single one of those pixels...
To capture the full brightness range of natural scenes, cameras automatically adjust the exposure value which causes the brightness of scene points to change from frame to frame. Given such a video sequence, we introduce a system for tracking features and estimating the radiometric response function of the camera and the exposure difference between frames simultaneously. We model the global and nonlinear...
