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...
The anomalies of power equipment can be founded using temperature changes compared to its normal state. In this paper we present a system for visualizing temperature changes in a scene using a thermal 3D model. Our approach is based on two precomputed 3D models of the target scene achieved with a RGB-D camera coupled with the thermal camera. The first model contains the RGB information, while the...
In this paper, we will present methods for camera pose estimation for mixed and diminished reality visualization in FTV application. We first present Viewpoint Generative Learning (VGL) based on 3D scene model reconstructed using multiple cameras including RGB-D camera. In VGL, a database of feature descriptors is generated for the 3D scene model to make the pose estimation robust to viewpoint change...
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...
This paper presents a prototype of virtual transparency on a hand-held device. The prototype is restricted to such device with no additional material to show that a semblance of virtual transparency can be achieved with today's smartphones and has been designed be as simple as possible to use. The user's head is tracked using the front camera and the eyes co-ordinates are estimated from the head position...
In this paper, we propose an approach for generating free viewpoint videos based on multiple depth and color cameras to resolve issues encountered with traditional color cameras techniques. Our system is based on consumer products such as Kinect that does not provide satisfying quality in terms of resolution and noise. Our contribution is then to propose a full pipeline for enhancing the depth maps...
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...
