五、主持人：信息与通信工程学院 武俊杰 教授
六、内容简介：
In the Polarimetric Synthetic Aperture Radar (PolSAR) literature, the approaches to coherent and incoherent data interpretation are bifurcated. In a bid to unify these approaches, a novel Scattering Power Factorization Framework (SPFF) using a geodesic distance (for measuring dissimilarity between two Kennaugh matrices) will be discussed. The SPFF is highly flexible in terms of the input scattering models and provides non-negative power in accordance with the similarity of observation with different scattering mechanisms. Besides, it paves the way for direct computation of roll-invariant parameters, application-specific indices for urban and agricultural studies, which are more dynamic in range in comparison to its counterparts in PolSAR literature. The talk will also elaborate on the versatility of the geodesic distance as an important tool in multifarious PolSAR applications by virtue of its elegant properties.
七、主讲人简介：
Avik Bhattacharya (M’08-SM’16) received the integrated M.Sc. degree in Mathematics from the Indian Institute of Technology, Kharagpur, India, in 2000 and the Ph.D. degree in remote sensing image processing and analysis from Télécom ParisTech, Paris, France, and the Ariana Research Group, Institut National de Recherche en Informatique et en Automatique (INRIA), Sophia Antipolis, Nice, France, in 2007.
He is currently an Associate Professor at the Centre of Studies in Resources Engineering, Indian Institute of Technology Bombay (CSRE, IITB), Mumbai, India. Before joining IITB, he was a Canadian Government Research Fellow at the Canadian Centre for Remote Sensing (CCRS) in Ottawa, ON, Canada. He received the Natural Sciences and Engineering Research Council of Canada visiting scientist fellowship at the Canadian national laboratories, from 2008 to 2011. His current research interests include SAR polarimetry, statistical analysis of polarimetric SAR images, applications of Radar Remote Sensing in Agriculture, Cryosphere, Urban and Planetary studies.
Dr. Bhattacharya is the Editor-in-Chief of IEEE GEOSCIENCE AND REMOTE SENSING LETTERS (GRSL). He was an Associate Editor of IEEE GEOSCIENCE AND REMOTE SENSING LETTERS. He has been the Guest Editor of the special issue on «Applied Earth Observations and Remote Sensing in India» in IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING (J-STARS), 2017. He is one of the guest editors of the special stream on «Advanced Statistical Techniques in SAR Image Processing and Analysis» in IEEE GEOSCIENCE AND REMOTE SENSING LETTERS, 2018. Dr. Bhattacharya is one of the subject heads of «Remote Sensing Imagery» under the field «Image» in the Encyclopédie des Sciences, ISTE-WILEY, UK. He is the Founding Chairperson of the IEEE Geoscience and Remote Sensing Society (GRSS) Chapter of the Bombay Section. He is currently leading the Microwave Remote Sensing Lab (www.mrslab.in) at CSRE, IITB.
