[...]... AIMS AND SCOPE OF DEVELOPMENTS IN PALEOENVIRONMENTAL RESEARCH SERIES Paleoenvironmental research continues to enjoy tremendous interest and progress in the scientific community The overall aims and scope of the Developments in Paleoenvironmental Research book series is to capture this excitement and document these developments Volumes related to any aspect of paleoenvironmental research, encompassing... as diatom and coccoliths, grain size, grain morphometry, sediment fabric Chemical and mineralogical data can be inferred from images of tools such as XRF-Scanning, IR-Scanning, and energy and wavelength dispersive spectrometry Other tools used are X-radiography, core scanning, non-normal scanning, optical and electron microscopy An international group of scientists, mainly marine and lacustrine sedimentologists,... researchers in the 90’s Soil scientists, especially micromorphologists, have been very active in the development of new image analysis tools (e.g., Terribile and Fitzpatrick (1992), VandenBygaart and Protz (1999), Adderley et al (2002)) The growing interest for image analysis in Earth Sciences is revealed by the increasing number of initiatives to bring image analysis into the spotlight Without being... - review and illustrate the wide range of quantitative information that can be obtained using image analysis techniques by showing case studies; - show improvements that high-resolution studies using image analysis techniques can bring about in paleoenvironmental reconstructions and in our understanding of environmental changes In order to achieve these goals, the DPER volume 7 is divided into three... changing hardware and software Metadata It is critical to record as much information as possible regarding the factors that can in uence the quality of images They include among other things, the characteristics and settings of the acquisition device (e.g., depth of field, current intensity in a SEM filament) and any event occurring during the working session such as a power failure The calendar of working... improvements in acquisition technologies, computing power and storage capacity have made sedimentary image processing increasingly viable for many applications in paleoenvironmental analysis An essential first step in sedimentary image analysis research is the acquisition of high quality images that are suitable for the research objectives The diversity of available image acquisition and processing systems... varied interests and the resources available to individual researchers Successful image acquisition requires substantial planning and consideration of the inherent limitations of the selected acquisition method Clearly, poor 11 P Francus (ed.) 2004 Image Analysis, Sediments and Paleoenvironments Kluwer Academic Publishers, Dordrecht, The Netherlands 12 LAMOUREUX AND BOLLMANN quality or substandard imagery... extracting quantitative information from sedimentary images (e.g., enhancement, calibration, and segmentation), the reader is referred to the other chapters that follow in this volume Image acquisition and paleoenvironmental research It is tempting to begin using image analysis for a variety of paleoenvironmental research with relatively little consideration of the image acquisition process Indeed,... In Chapter 10, Ojala outlines how to acquire the best possible X-radiographs of thin impregnated slabs of laminated sediments in order to perform the counting and quantification of the laminae Then, Chapter 11, by Soreghan and Francus, reviews the issues during the acquisition of images using scanning electron microscopes in backscattered mode, and illustrates the analysis of thin-sections of an old consolidated... meetings on the subject (e.g., Geological Society of London, London, UK, September 1993, and Geovision held in Liège, Belgium, in May 1999), an increasing number of papers in journals such as Computers & Geosciences, and books (e.g., De Paor (1996)) In the second volume of the Developments in Paleoenvironmental Research (DPER) series, a chapter by Saarinen and Pettersen (2001) was already devoted to image . alt="" Image Analysis, Sediments and Paleoenvironments Developments in Paleoenvironmental Research VOLUME 7 Image Analysis, Sediments and Paleoenvironments Edited by Pierre Francus Springer eBook.
