In this paper, we propose an efficient framework for reducing noise and holes in depth map captured with an RGB-D camera. This is performed by applying plane fitting to the groups of points assimilable to planar structures and filtering the curved surface points. We present a new method for finding global planar structures in a 3D scene by combining superpixel segmentation and graph component labeling...
Usually, relighting techniques require knowledge about the shape of the target object and the lighting environment. The quality of the result is highly dependent on the normals of the object because they are used in the computation of the illumination. In this paper, we propose a new relighting approach for arbitrarily shaped objects using an RGB-D camera such as the Microsoft's Kinect. The depth...
Beginners need a long time before being able to play correctly violin. Learning the bowing technique appears to be a difficult task and retains most of the attention of beginners. Besides this point, the finger placement is also an important part of the learning but often under estimated. One difficulty is that the fingerboard of the violin does not have frets. In this on-going work, we present a...
Spatial augmented reality extends augmented reality by projecting virtual data directly on a target surface, but requires to calibrate a projector-camera system. This paper introduces a free-calibration projector-camera system for spatial augmented reality with a planar surface. A pattern is projected on the target surface that can be freely moved. The main difficulty is to make the projected image...
Stereoscopic displays are becoming very popular since more and more contents are now available. As an extension, auto-stereoscopic screens allow several users to watch stereoscopic images without wearing any glasses. For the moment, synthetized content are the easiest solutions to provide, in realtime, all the multiple input images required by such kind of technology. However, live videos are a very...
