MarineSAR: Tracking Marine Oil Spills by RADARSAT

Ocean pollution caused by oil-spills is currently considered a significant environmental hazard. Synthetic aperture radar (SAR) carried by Earth observing satellites have proven to be a powerful tool for monitoring oil-spills in marine waters. This talk will provide a comprehensive overview of currently available satellite SAR sensors and SAR image analysis approaches to oil-spill monitoring with a focus on dark-spot detection. Dark-spot detection is a fundamental step in computerized marine oil-spill detection systems. Automated detection of dark-spots using SAR imagery is a very challenging task, primarily due to the presence of multiplicative noise known as speckle. This talk will present a novel two–phase automated segmentation approach, namely the total variation optimization segmentation (TVOS), in which, spatial, intensity, and gradient differences are used to effectively remove the speckles while preserving the boundaries of oil areas. The quantitative assessment of the dark-spot detection results obtained using both synthetic and real COSMO-SkyMed SAR images demonstrated that the TVOS method consistently reached a kappa value near 1 throughout all the noise levels, indicating good matches with the reference data. Also, the proposed dark-spot detection approach presents better segmentation results and takes less computing time.

Energy Informatics

Informatics is the discipline that deals with the notion, storage, and processing of all that can be considered as information. Within the last decades, informatics has developed sophisticated modelling, analysis, and optimization techniques for a diverse set of phenomena found in the domain of processing information but also found in physical domains. Energy informatics is a relatively new field of informatics. It deals with the application of the methods and tools developed in informatics to all aspects and domains that deal with energy in a broad sense. As is the case for other fields such as bio informatics or legal informatics, it is expected that the systematic application of informatics for energy aspects will advance this field considerably. In this presentation, we will give an introduction to the field of energy informatics. We will discuss the characteristics of energy informatics, both by looking at different applications and working out their challenges as well as by looking at different fields of computer science and how they can contribute to solving the challenges in energy informatics.

Simultaneously Fitting and Segmenting Multiple-Structure Data with Outliers

Robust statistical methods play a vital role in many activities in computer vision research. When engaged in the applications in a computer vision context, it is important to recognize that it is almost unavoidable that data are contaminated by noise and outliers (due to faulty feature extraction, segmentation errors, etc) and it is also likely that the data will include multiple structures. Thus, it has been widely acknowledged that all algorithms in computer vision should be robust for accurate estimation. To fit a model to noisy data (with a large number of outliers and multiple structures) is still a major and challenging task within the computer vision communities. In this talk, I will introduce some of my recent work on robust statistics and its various applications, including line fitting, circle fitting, range image segmentation, homography estimation and two-view based motion segmentation, etc.



Hanzi Wang is currently a Distinguished Professor and a “Min Jiang Scholar” at Xiamen University (XMU), China. He is a director of the center for Pattern Analysis and Machine Intelligence and the Computer Vision Laboratory at XMU. He has been an Adjunct Professor at the University of Adelaide, Australia since 2010. He was a Senior Research Fellow (2008-2010) at the University of Adelaide, Australia; an Assistant Research Scientist (2007-2008) and a Postdoctoral Fellow (2006-2007) at the Johns Hopkins University; and a Research Fellow at Monash University, Australia (2004-2006). He received the Ph.D. degree in Computer Vision from Monash University, Australia where he was awarded the Douglas Lampard Electrical Engineering Research Prize and Medal for the best PhD thesis. His research interests are concentrated on computer vision and pattern recognition including visual tracking, robust statistics, model fitting, object detection, video segmentation, and related fields. He has published more than 50 papers in major international journals and conferences including the IEEE TPAMI, IJCV, IEEE TMI, ICCV, CVPR, ECCV, NIPS, MICCAI, etc. He is an Associate Editor for IEEE Transactions on Circuits and Systems for Video Technology (T-CSVT) and he was a Guest Editor of Pattern Recognition Letters (September 2009).

Robust Wireless Transmitting Techniques over E- HealthCare Environments

Recently e-healthcare is attracted much attention from research unit, universities and industry. There some important problems for us to need to solve. One of most important key points in this infrastructure is how to keep robust transmitting through modern short distance wireless communication network so that exact healthcare services are carried out.
In this talk one low complexity, low power modulation and demodulation transmitting technique, namely FM-DCSK UWB is introduced in this e-healthcare environment. We will describe and analyze the model how to implement the robust wireless transmitting through modern signal processing (STBC, MIMO, Cooperation Communications, ARQ) over indoor or WBAN. Meanwhile we will provide one new joint source and channel coding scheme to enhance the quality of wireless transmitting over AWGN, which is benefit to improve the robust transmitting over e-healthcare environments.
