People

The current Seascape is the result of a multidisciplinary effort with contributions from engineers in computer vision and marine ecologists. Initialy, the objective was to adapt a segmentation software for aerial photographs to seabed images. From the marine ecology perspective, there was a need to develop automatic or semi-automatic analytical techniques to calculate accurate estimates of benthic cover of complex marine benthic communities. Since mid-2007 there have been a core group to write and develop Seascape. The group members are:

 

Anton Albajes-Eizagirre received a technical BSc on Computer Science from the Universitat de Lleida (UdL) in 2003. Afterwards, he spend two years at University Politécnica de Catalunya taking courses from the engineering BSc in computer science. In 2005 he switched to Universitat Pompeu Fabra (UPF) where he obtained the engineering BSc in 2007. On the premises of those studies he spent six months at Boston College within an exchange program. In 2009 he received his Master Degree on the Cognitive Systems and Interactive media at UPF. After graduating from UdL he collaborated for a year with the Applied Mathematics Department in the same institution. He worked at the Technology Department at UPF as a research assistant. Anton adapted and upgraded the original libraries to the analysis of marine benthic communities. Since 2009 he is working in Starlab as a researcher

 


 

Dr. Didier Boldo is now a researcher at Électricité de France EDF R&D. His main research interests are image and signal processing. His principal research is 3D reconstruction of man made objects and metrology using images (photogrammetry).

 


 

Dr. Montse Demestre is a Scientific Titular at the Marine Sciences Institute of Barcelona (ICM-CSIC). Her research interest lies in the study ecology of benthic communities, especially fisheries biology and population dynamics of Mediterranean fisheries. One of her principal research lines is the study of the impact of demersal fishing gears on the benthic ecosystem. She has participated in many oceanographic expeditions in the Atlantic and Pacific Oceans and the Mediterranean Sea by using ROVs.

 


 

Dr. Joaquim Garrabou is a Scientific Investigator at the Institute of Marine Sciences of Barcelona (ICM-CSIC) since September 2008. He worked at the Centre d’Océanologie de Marseille (COM-CNRS) for the last nine years. His main research lines focuses on the study of global change to marine rocky benthic communities in the Mediterranean Sea. He has participated in many littoral campaigns in the Mediterranean Sea using scuba diving. He works with long term image data series to detect and quantify changes over long spatial and temporal scales.

 


 

Dr. Laurent Gigues is now a researcher at Softkinetic, SA/NV, in Brussels, Belgium. He was a former researcher at CREATIS and MATIS image and signal processing labs, in France. During his PhD at MATIS lab, entitled “Modèles Multi-Echelles pour la Segmentation d’Images”, he wrote the original libraries that are invoked during the execution of Seascape. His main interests are image analysis, image segmentation, neural networks, gesture recognition, 3D tracking, inverse kinematics

 


 

Dr. Josep-Maria Gili is a Research Professor at the Marine Sciences Institute of Barcelona (ICM-CSIC). His research lines foucses on the study of littoral marine ecosystems and continental platform by applying multidisciplinary approaches. He participated in numerous oceanographic expeditions to study the benthic communities of Antarctica and the Mediterranean Sea by using ROVs and submarines.

 


 

Dr. Emilie Le Hir is now a researcher at the Institut Geographique National (IGN Espace) in Toulouse, France. Her main interests are image analysis and photogrammetry

 


 

Dr. Jaume Piera is a Scientific Titular at the Marine Technology Unit (UTM-CSIC). His research lines focuses on the research and technological innovation in instrumentation in Marine Sciences. He has a large experience in the development of new oceanographic sensors to study the the physical-chemical processes that affects the water column and the seafloor and algorithm systems to analyze data.

 


 

Thomas Prelot obtained his Engineer degree from the “Ecole d’Ingénieurs de l’Innovation, des Sciences de l’Energie et des Technologies Avancées ESME-Sudria) in France. Thomas adapted and upgraded the original libraries to the analysis of marine benthic communities during his Master research at the Institut Geographique National (IGN) and at the Centre d’Océanologie de Marseille (COM-CNRS).

 


 

Dr. Aureli Soria-Frisch received the 'Eng. Tècnic en Telecomunicacions' degree (BSc) from University Ramon Llull (1992), the 'Eng. de Telecomunicació' degree (MSc) from the Politechnical University of Catalonia– UPC (1995), and the 'Dr.-Ing.' degree (PhD) from the Technical University Berlin. Between 1996 and 2005 he worked at the Fraunhofer IPK (Berlin), where he participated in several funded research and industrial projects as research scientist and project leader. After working for 3 years at the Universitat Pompeu Fabra, he joined Starlab in 2008. His research interest is focused on the fields: data and multi-sensory fusion, computational intelligence for data analysis, and soft computing for image processing and analysis. He is author of eight journal papers, five book chapters, and several conference papers

 


 

Dr. Núria Teixidó is a postdoctoral fellow at the at the Institute of Marine Sciences of Barcelona (ICM-CSIC). Her main research activity is related to the ecology of benthic communities, focusing in their structure and dynamics under the influence of disturbances associated to global change. She has participated in oceanographic expeditions in Antarctica and in many littoral campaigns in the Mediterranean Sea using scuba diving. Her research focuses on biodiversity and temporal patterns of Mediterranean benthic communities by using photographic image analyses. This image database allows detecting and quantifying changes over long spatial and temporal scales.
