Mapping the interior of a building is a nice step to obtain the description of that building. In that context, this article presents the use of a low cost 3D sensor, the Microsoft Kinect for Windows v1, associated to RGBDSLAM in order to perform that mapping. Even if the method is well-known and has showed its performance, its use is not as simple as it looks like. Limitations of both the sensor and...
The paper presents a method to assist the landing of an Unmanned Aerial Vehicle (UAV) on a moving Unmanned Ground Vehicle (UGV). The measurement of the relative position of the UAV and the UGV is carried out by a cheap USB camera. The paper deals with the list of the difficulties of such a system which have to be taken into account and develop ideas on how to overcome them. The solution of the key...
This article focuses on the ability to use a robot with a low cost 3D Scanner (Kinect) in an indoor environment to do a mapping of different rooms in a building and to be able to localize itself when going back to the same room. This method uses SIFT points (points of interest in images) to be able to reconstruct the environment in 3D and uses these SIFT points to identify the localization of the...
EROS is the largest database in the world of high resolution art pictures. The TSAR project is designed to open it in a secure, efficient and user-friendly way that involves cryptography and water-marking as well as compression and region-level representation abilities. This paper more particularly addresses the two last points. The LAR codec is first presented as a suitable solution for picture encoding...
This paper presents a full multiresolution lossless coding method, with advanced semantic scalability. In particular, a reversible form of the usual Walsh Hadamard Transform (RWHT) is first introduced as an alternative to standard lossless transform. A pyramidal representation and decomposition schemes involving this basic transform are then proposed. Significant improvements are obtained using two...
