[Termes IGN] zone urbaineRésumé : (Auteur) A main problem of hard image segmentation is that, in complex landscapes, such as urban areas, it is very hard to produce meaningful crisp image-objects. This paper proposes a fuzzy approach for image segmentation aimed to produce fuzzy image-regions expressing degrees of membership of pixels to different target classes. This approach, called Fuzzy Image-Regions Method (FIRME), is a natural way to deal with the inherent ambiguity of remotely sensed images. The FIRME approach comprises three main stages: (a) image segmenta-tion which creates fuzzy image-regions, (b) feature analysis which measures properties of fuzzy image regions, and (c) classification which produces the intended land-cover classes. The FIRME method was evaluated in a land-cover classification experiment using high spectral resolution imagery in an urban zone in Bogota, Colombia. Results suggest that in complex environments, fuzzy image segmen-tation may be a suitable alternative for GEOBIA as it produces higher thematic accuracy than the hard image segmentation and other traditional classifiers.

[Termes IGN] visualisation 3DRésumé : (Auteur) Modern terrestrial laser scanners (TLS) generate between 10 and 50 million 3D coordinates per minutes : about 500Mbytes of data. Together with high-resolution images for texturing purposes, this is enough information to choke high-end PCs running commercial software. The National Research Council in Canada has developped a framework for extracting information from very large TLS and imagery datasets, an evolution demonstrated in the Erechtheion project. This monument has been modelled in the 3D to a spatial resolution of 2mm. The fully textured 3D model containing 348 million polygons can be interactively visualised and analysed in real time.

[Termes IGN] surveillanceRésumé : (Auteur) The paper concerns a part of the activity of the Istituto per i Beni Archeologici e Monumental! (IBAM) in the "Iraq Virtual Museum" Project of the Consiglio Nazionale delle Ricerche (CM?); in partic-ular, it is focused on the activities for the creation of the section "Archaeological Sites", finalized to the contextual ization of finds stored in the Baghdad Museum. During this work the contribution of high resolution satellite images (Ikonos-2, QuickBird-2, World View-1) was very important, which were taken in 2001 - 2008 and used to document the modern situ-ation of the archaeological areas and tor monitoring their pre/post second Gulf War situations; very important were also the high resolution satellite pho-tos taken by USA spy satellites in 1960s and 1970s, that are useful for monitoring the transformations of the most important archaeological Iraqi areas in the last 30-40 years, before the first Gulf War.
The multitemporal remote sensing data used in the Project for the contextualization of archaeolog-ical finds, also allowed to discover new data about ancient topography, urban layout and paleo-environmental context of many ancient cities and archaeological areas; for the study of these sites and territories some aerial photos are also used, taken in the 1920s, 1930s and 1940s by RAF pilots. In some cases, instead, the orthorectification of the recent satellite images and the vectorization of all archaeological remains and traces visible in the satellite images, allowed the upgrade of existing archaeological maps with new data about ancient urban layouts, monuments and roads. An illustra-tive example is that of Seleucia on the Tigris, whose urban layout has been studied in the 20s, 30s and 60s of the 20th century with the use of aerial photographs; the analysis and processing of several satellite images, taken in different moments between 1965 and 2007, allowed to acquire new data on the regular outline of the city's blocks, and to create a new archaeological plan of the site.Numéro de notice : A2009-565 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=30194

[Termes IGN] transformation intensité-teinte-saturationRésumé : (Auteur) Synthetic aperture radar (SAR) imaging can be a feasible alternative or a complement to traditional optical remote sensing techniques because it does not depend on solar illumination and weather conditions. The high spatial resolution of SAR, such as the Intermap STAR-3i airborne SAR image with 1.25 m spatial resolution, makes it applicable for high spatial resolution mapping purposes. However, difficulties sometimes exist in the interpretation of SAR images. Image fusion presents an alternative to improve the interpretability of SAR images by fusing the color information from moderate spatial resolution multispectral (MS) images. In this paper, a new fusion method based on the integration of wavelet transform and IHS (Intensity, Hue, and Saturation) transform is proposed for SAR and MS fusion to maintain the spectral content of the original MS image while retaining the spatial detail of the high-resolution SAR image. Three data sets are used to evaluate the proposed fusion method: two sets are airborne SAR images with MS images at different spatial resolutions; the other set is a Radarsat image with a Landsat TM image. The fusion results are evaluated visually and statistically. The evaluation shows that successful results are achieved in the fusion of all SAR and MS images from a variety of sensors with significant spatial and spectral variations by using the proposed image fusion method.
