From Hussein.Yahia at inria.fr Fri Feb 9 03:54:26 2007 From: Hussein.Yahia at inria.fr (Hussein Yahia) Date: Fri Feb 9 03:49:34 2007 Subject: [ece8000] PhD offer at INRIA, near Paris, France: Glint and solar artefacts elimination in oceanographic satellite imagery Message-ID: <200702091054.26968.Hussein.Yahia@inria.fr> Title: Glint and solar artefacts elimination in oceanographic satellite imagery. Limit date: March 10, 2007. Web page: http://www-rocq.inria.fr/~yahia/PhD-Offer1.html Subject description: New research areas in the domains of multiscale signal analysis provides new ways of research for the analysis of geophysical acquisitions, notably satellite acquisitions in oceanography. These methods allow the determination of super-geometric structures in the signal, these structures being strongly related to the statistical properties of the signal. These multiscale methods have a strong potential to solve the problems of glint and other artefacts elimination in satellite oceanographic acquisitions. The PhD is centered around the following problematics: -Use of the reconstruction properties to provide new methods for glint elimination and missing data in satellite oceanographic acquisitions, -Generalisation to the case of temporal datasets. During the PhD, theoretical results will be implemented into a software API called FluidExponents, developped jointly by INRIA (National Research Institute in Computer Science and Applied Mathematics, France) and ICM (Institute for Marine Sciences, Barcelona, Spain). FluidExponents is intented to be diffused in the geophysics community. The applicant will make visits to ICM at Barcelona during the PhD. Skills Knowledge in remote sensing and signal processing. Knowledge in wavelet theory is a plus. Knowledge of a programming langage. We will give the applicant a training in the developpment in a modern IDE (Integrated Development Environment) like Eclipse. Person to contact Please send a CV (1 or 2 pages) to Mr. H. Yahia Hussein.Yahia@inria.fr, Tel: +33 (1) ?39 63 53 57 INRIA-Rocquencourt, BP 108 78153 Le Chesnay Cedex, France. Location The PhD is done at INRIA-Rocquencourt, near Paris. The PhD is made in collaboration with the CNES (French Center for Spatial Studies).

These methods allow the determination of super-geometric structures in the signal, these structures being strongly related to the statistical properties of the signal and to the dynamics of the oceanic flow. From recent results about the advection of singularity exponents in the oceanic flow, this formalism has a strong potential in the analysis of ocean dynamics. The PhD is centered around the following problematics: -Use of the reconstruction properties to provide new methods for the quantitative evaluation of surface ocean dynamics from Sea Surface Temperature (SST) and altimery satellite acquisitions. Combined optical flow on super-geometric structures and reconstruction properties. -Use of the MMF for ocean colour acquisitions: patchiness and sub-mesoscale phenomena, algae blooms and upwellings.
