In this paper, we present a vision-based humancomputer interaction system merely consisting of a projector and a single camera, which is no longer limited to traditional displaying but allowing users to touch on any projected surfaces for interaction. The challenge of bare-hand touch detection in projector-camera system is to recover the depth from user's fingertip to projector with monocular vision...
Natural image matting is a useful and challenging task when processing image or editing video. It aims at solving the problem of accurately extracting the foreground object of arbitrary shape from an image by use of user-provided extra information, such as trimap. In this paper, we present a new sampling criterion based on random search for image matting. This improved random search algorithm can...
