Most morphological operators use a unique structuring element, possibly at different scales, to describe an object. In addition, morphological algorithms are often restricted to 1D structuring elements, combinations of 1D elements, or isotropic structuring elements (like circles), because of the lack of methods directly applicable to 2D structuring elements. While these descriptors have proved useful in the past, we propose an alternative that uses the list of maximal rectangles contained in a set X. In particular, we focus on an opening that preserves large rectangles contained in a set X and on its companion 2D algorithm that builds a list of all the maximal rectangles that fit inside an arbitrary set X. This list is the base of new descriptors that have been used successfully for machine learning tasks. [less ▲]

The aim of this paper is to efficiently detect and identify the building changes from newly registered very high spatial resolution (VHSR) image by comparing with outdated map. The whole process is performed mainly on four steps. First, the image was segmented to generate primitives, which are then represented by a feature vector composed from spectral, geometric, textural and contextual attributes. Thereafter, tree-based ensemble methods (Bagging, Random Forest and Extremely Randomized Trees) are used in a classification step. The final objects' prediction is deducted thanks to better classifier error rate. Last, a post classification change detection step allows to identify the segments which represent building changes. The data used in this research concerns the city of Rabat (Morocco). A Quickbird image has been used with an old map at the scale of 1:10,000. Regardless of the quality of the detected buildings' shape, the method achieves good rates of completeness (94%) and correctness (92%). [less ▲]

While 3D cinema is becoming more established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant interest. In order to carry out such experiments, it is necessary to have an appropriate s-3D movie and its corresponding 3D audio track. This paper presents the procedure followed to obtain this joint 3D video and audio content from an existing animated s-3D film, problems encountered, and some of the solutions employed. [less ▲]

Geological and hydrogeological data are expensive to obtain in the field but are crucial for specific hydrogeological studies, from hydrogeological water balances to groundwater flow modelling and contaminant transport, or for more integrated environmental investigations where groundwater plays a role. In this context, hydrogeological data are collected, transformed and exchanged at different scales, from local to international levels and between numerous institutions ranging from environmental consulting companies to the national and international environmental administrations. To guarantee that these exchanges are possible and meaningful, a clear structure and meta-information on applied hydrogeological data models is required. To make one step towards seamless management of groundwater projects, a new hydrogeological data model has been developed: Hg2O. It is described using object-oriented paradigms and it follows the recommendations of the International Organization for Standardization (ISO/TC211), the Open Geospatial Consortium (OGC), and the European Geospatial Information Working Group. Hydrogeological features are organized in packages of spatial feature datasets. The observations and measurements related to these features are organized in a seperate package. A particular focus is on specialized hydrogeological field experiments such as hydraulic and tracer tests. Two first implementations in the proprietary desktop ArcGIS environment and in the open-source web-based Web2GIS platform are presented, focusing on their respective standards support. [less ▲]
