Classification of Remote Sensing Images Using Morphological Profiles
Almost a decade has passed since the concept of morphological profile (MP) was defined for the analysis of panchromatic remote sensing images. From that time, the MP has largely proved to be a powerful tool able to model spatial information (e.g., contextual relations) of the image by extracting structural features (e.g., size, geometry, etc.) from the objects present in the scene. The MP processes an input image with a sequence of progressively coarser filters. This leads to a stack of filtered images showing an increasing simplification of the scene. The evaluation of how the objects in the image interact with the filters gives information on the objects structural features. The great amount of contributions present in the literature that address the application of MP to many tasks (e.g., classification, object detection, segmentation, change detection, etc.) and to different types of images (e.g., panchromatic, multispectral, hyperspectral) proves how MP is still an effective and modern tool. Moreover, many variants, extensions and refinements of its definition have also appeared stating that the MP is still under continuous development. This paper presents the MP from its early definition to the recent advances based on morphological attribute filters. The morphological attribute filters are used in classification of panchromatic and hyperspectral images and the obtained results are compared to results when classifiers are applied without such processing.
Jon Atli Benediktsson (S’84.M’90.SM’99.F’04)
received the Cand.Sci. degree in electrical engineering from the University of Iceland, Reykjavik, Iceland, in 1984 and the M.S.E.E. and Ph.D. degrees from Purdue University, West Lafayette, IN, in 1987 and 1990, respectively. He is currently a Pro Rector for academic affairs and a Professor of electrical and computer engineering with the University of Iceland. He has held visiting positions with the Department of Information and Communication Technology, University of Trento, Trento, Italy, since 2002; the School of Computing and Information Systems, Kingston University, Kingston upon Thames, U.K., during 1999.2004; the Joint Research Centre of the European Commission, Ispra, Italy, in 1998; the Technical University of Denmark, Lyngby, Denmark, in 1998; and the School of Electrical and Computer Engineering, Purdue University, in 1995. In August 1997, he was a Fellow with the Australian Defence Force Academy, Canberra, A.C.T., Australia. From 1999 to 2004, he was the Chairman of the energy company Metan Ltd. He was also the Chairman of the University of Iceland’s Science and Research Committee from 1999 to 2005. Since 2006, he has been the Chairman of the University of Iceland’s Quality Assurance Committee. His research interests include remote sensing, pattern recognition, machine learning, image processing, biomedical engineering, and signal processing, and he has published extensively in those fields. Dr. Benediktsson was the Past Editor and is currently an Associate Editor for the IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING (TGARS) and an Associate Editor for the IEEE GEOSCIENCE AND REMOTE SENSING LETTERS. He coedited (with Prof. D. A. Landgrebe) a Special Issue on Data Fusion of TGARS (May 1999) and (with P. Gamba and G. G. Wilkinson) a Special Issue on Urban Remote Sensing from Satellite (October 2003). From 1999 to 2002, prior to being an Editor, he was an Associate Editor for TGARS. From 1996 to 1999, he was the Chairman of GRSS Technical Committee on Data Fusion and was elected to the Administrative Committee of the GRSS for the terms 2000.2002 and 2008.2010. He is currently, the Executive Vice President of GRSS. In 2002, he was appointed as Vice President of Technical Activities of GRSS, and in 2008, he was appointed as Vice President of Professional Activities of GRSS. He was the founding Chairman of the IEEE Iceland Section and served as its Chairman from 2000 to 2003. He was a member of a NATO Advisory Panel of the Physical and Engineering Science and Technology Subprogram (2002.2003). He was a member of Iceland’s Science and Technology Council (2003.2006) and a member of the Nordic Research Policy Council (2004). He received the Stevan J. Kristof Award from Purdue University in 1991 as an outstanding graduate student in remote sensing. In 1997, he was the recipient of the Icelandic Research Council’s Outstanding Young Researcher Award. In 2000, he was granted the IEEE Third Millennium Medal. In 2004, he was a corecipient of the University of Iceland’s Technology Innovation Award. In 2006, he received the yearly research award from the Engineering Research Institute, University of Iceland. In 2007, he received the Outstanding Service Award from the IEEE Geoscience and Remote Sensing Society. He is a member of Societas Scinetiarum Islandica and Tau Beta Pi.
