Oceans from Space – Venice 2010
Dear Colleagues,
Here is, at long last, the official announcement, call for registration and call for papers of the “Oceans from Space” 4th edition. Please note that all the details concerning Venice 2010 (including venue / transportations / accommodations, preliminary programme, on-line registration and submission of contributions) are available on the Symposium website:
http://oceansfromspace.jrc.ec.europa.eu/
As you will see, not all the information provided on the website (the programme, in particular) are final. Updates will be posted as soon as they become available. In the meantime, let me bring to your attention the 31 January 2010 deadline, which has been set for both the early-bird registration, at a reduced fee, and the submission of contributions.
I’m sending this brief message to the usual Venice 2000 emailing list, with some (many, actually) additions, but I trust that you will all do your part in spreading the news about the most recent developments re the Symposium.
Thank you all for your support. The Organizing Committee would be even more grateful, if you could help out by registering, and paying the relevant fee, at a VERY EARLY stage: Venice is more expensive than even, these days, but we might be able to keep costs low, if we have enough resources to book the required Symposium services well in advance. Stand by for more information to appear on our dedicated website.
With my best personal rest regards,
Vittorio Barale

Spectral mixture analysis (also called spectral unmixing) has been an alluring exploitation goal since the earliest of imaging spectroscopy. No matter the spatial resolution, the spectral signatures collected in natural environments are invariably a mixture of the signatures of the various materials found within the spatial extent of the ground instantaneous field view of the imaging instrument. The availability of hyperspectral imagers with a number of spectral bands that exceeds the number of spectral mixture components has fostered research efforts targeted at spectral unmixing, adopting a perspective similar to that of blind source separation (BSS): Given a set of spectral vectors acquired from a given area, spectral unmixing aims at inferring the pure spectral signatures, called endmembers, (i.e., the mixing matrix in a BSS problem), and the material fractions, called fractional abundances, at each pixel (i.e., the sources in a BSS problem). Since each observed spectral signal is the result of an actual mixing process, it is expected that the driving abundances obey two constraints, i.e. all abundances should be nonnegative, and the sum of abundances for a given pixel should be unity. The latter constraint implies that the fractional abundances are statistically dependent. Furthermore, the inference and validation of a correct suite of endmembers, and imposing such constraints in practical applications (including those in which fewer spectral bands are available) have remained a challenging and elusive goal for the past twenty years. A standard technique for spectral mixture analysis is linear spectral unmixing, which assumes that the collected spectra at the spectrometer can be expressed in the form of a linear combination of endmembers weighted by their corresponding abundances. Although the linear model has practical advantages, such as ease of implementation and flexibility in different applications, nonlinear spectral unmixing may best characterize the resultant mixed spectra for certain endmember distributions, such as those in which the endmember components are randomly distributed throughout the field of view of the instrument. In those cases, the mixed spectra collected at the imaging instrument is better described by assuming that part of the source radiation is multiply scattered before being collected at the sensor. The distinction between linear and nonlinear spectral mixture analysis, as well as the different processing and applicationoriented aspects of the unmixing chain, have been studied quite widely in recent years, and experienced great challenges. In the Guest Editors’ opinion, it is time to bring all the studies together in the form of a Special Issue specifically devoted to this topic. This special issue on Spectral Unmixing of Remotely Sensed Data is intended to present the current state-of-the-art and the most recent developments in the area of spectral mixture analysis. The special issue is expected to bring together experts from many different institutions to provide a remarkable sample of latest-generation techniques in the field. Specifically, the focus Proposal for a Special Issue on Spectral Unmixing of Remotely Sensed Data of the special issue will be on recent developments in techniques and applications of spectral mixture analysis of data sets provided by hyperspectral imagers, which have substantially increased their spectral resolution (imagers with hundreds of narrow spectral channels are currently available and instruments with thousands of spectral bands are under development), thus producing a nearly continual stream of high-dimensional image data which demands fast and effective techniques for data interpretation with sub-pixel precision. As a result, the techniques covered by this special issue will comprise recent advances in the different parts of the processing chain for spectral mixture analysis of hyperspectral data, including dimensionality estimation, automatic calculation of the number of endmembers, unsupervised and semi-supervised endmember extraction (using spatial and/or spectral information), endmember fractional abundance estimation using both linear and nonlinear inversion, applications of spectral mixture analysis in environmental and military-oriented problems, and efficient implementation of spectral unmixing algorithms Combined, the topics addressed in this Special Issue are expected to provide an excellent snapshot of the state-of-the-art in the area, and to offer a thoughtful perspective on the potential and emerging challenges of applying spectral mixture analysis to the new generation of airborne and, particularly, satellite hyperspectral imaging instruments. Although analysis of hyperspectral data will be an important component of the Special Issue, contributions on spectral mixture analysis of other types of data will also be solicited. Specifically, particular attention will be given to the possibility of applying spectral unmixing concepts to scenes with moderate spectral resolution (multispectral), and to the use of spectral unmixing for data compression purposes.
