People Watching: Human Actions as a Cue for Single View Geometry
David Fouhey , Aude Oliva , Silvio Savarese
Video in druga učna gradiva
Oznake: computer science;computer vision
We present an approach which exploits the coupling between human actions and scene geometry. We investigate the use of human pose as a cue for single-view 3D scene understanding. Our method builds upon recent advances in still-image pose estimation to extract functional and geometric constraints abo ...

Beyond the line of sight: labeling the underlying surfaces
Ruiqi Guo , Aude Oliva , Silvio Savarese
Video in druga učna gradiva
Oznake: computer science;computer vision
Scene understanding requires reasoning about both what we can see and what is occluded. We offer a simple and general approach to infer labels of occluded background regions. Our approach incorporates estimates of visible surrounding background, detected objects, and shape priors from transferred tr ...

Depth Extraction from Video Using Non-parametric Sampling
Kevin Karsch , Aude Oliva , Silvio Savarese
Video in druga učna gradiva
Oznake: computer science;computer vision
We describe a technique that automatically generates plausible depth maps from videos using non-parametric depth sampling. We demonstrate our technique in cases where past methods fail (nontranslating cameras and dynamic scenes). Our technique is applicable to single images as well as videos. For vi ...

Multiple View Object Cosegmentation using Appearance and Stereo Cues
Adarsh Kowdle , Aude Oliva , Silvio Savarese
Video in druga učna gradiva
Oznake: computer science;computer vision;object recognition
We present an automatic approach to segment an object in calibrated images acquired from multiple viewpoints. Our system starts with a new piecewise planar layer-based stereo algorithm that estimates a dense depth map that consists of a set of 3D planar surfaces. The algorithm is formulated using an ...

Indoor Segmentation and Support Inference from RGBD Images
Nathan Silberman , Aude Oliva , Silvio Savarese
Video in druga učna gradiva
Oznake: computer science;computer vision
We present an approach to interpret the major surfaces, objects, and support relations of an indoor scene from an RGBD image. Most existing work ignores physical interactions or is applied only to tidy rooms and hallways. Our goal is to parse typical, often messy, indoor scenes into floor, walls, su ...
