Abstract
A method separates foreground from background in a sequence of images, by first acquiring the sequence of images and a depth map of a scene by a camera. Groups of pixels are determined based on the depth map. Then, the sequence of images is decomposed into a sparse foreground component, and a low rank background component, according to apparent motion in the sequence of images, and the groups.
Claims18
A method for separating foreground from background in a sequence of images, comprising steps of:
- acquiring the sequence of images and a depth map of a scene by a camera;
- and
- determining groups of pixels based on the depth map;
- and
- decomposing, according to an apparent motion in the sequence of images, and the groups, the sequence of images into a sparse foreground component, and a low rank background component, wherein the steps are performed in a processor connected a memory storing the sequence of images and the depth map.

A system for separating foreground from background in a sequence images, comprising:
- a camera for acquiring the sequence of images and a depth map of a scene;
- a memory storing the sequence of images and a depth map;
- and
- a processor connected to the memory for determining groups of pixels based on the depth map, decomposing, according to apparent motion in the sequence of images, and the groups, the sequence of images into a sparse foreground component, and a low rank background component, wherein the groups are depth based.
