We describe our experiments using a rolling swivel chair as a control/display platform for exploring multi-standpoint panoramic spaces, characterized not only by 360 degrees scenes, but also modestly navigable photorealistic spaces, enabled by multinode QTVR movies. Two markers are attached to a prototype chair one on each armrest. the markers' locations are tracked by application of image processing techniques to the video stream captured by a ceiling cam, deriving chair displacement and rotation. Using such chair-driven gestures, graphical windows egocentrically displaying the panned and displaced panoramic scene can be dynamically dilated in a Gut root window by active exploration.
Single image dehazing has been a challenging problem for following high-level computer vision task due to the terrible information distortion. We noticed that most of existing dehazing methods are tend to pay more att...
