IEEE AP/MTT/EMC/ED TURKEY CHAPTER SEMINAR SERIES -- SEMINAR 35
Speaker: Asst. Prof. Seniha Esen Yuksel, Hacettepe University
Topic: "Can You "See" the Target in the Shadow?"
Location: Middle East Technical University, Ankara, Turkey
Abstract: Hyperspectral cameras are a special set of cameras which collect hundreds of images from across the electromagnetic spectrum. In doing so, it is possible to label every single pixel based on its material content; such as asphalt, grass, water etc. This incredible information on materials can be used in a variety of fields from agriculture to astronomy, medical imaging and defense. However, one hurdle occurs when the light is simply not there to collect: targets hidden in shadow regions are very difficult to detect from hyperspectral images. One way to mitigate this problem is to detect the shadow areas using light detection and ranging (LiDAR) sensors, and to correct for the hyperspectral data in these regions. In this talk, we will first introduce the hyperspectral and LiDAR sensors and explain the physical radiance model. Then, we will describe our efforts to combine LiDAR and hyperspectral data in the shadow regions using the physical radiance model; and show that this significantly increases the target detection rates in shadow regions.
Bio: Seniha Esen Yuksel received the B.Sc. degree in electrical and electronics engineering from the Middle East Technical University, Ankara, Turkey, in 2003; the M.Sc. degree in electrical and computer engineering from the University of Loisville, Louisville, USA in 2005; and the Ph.D. degree in computer engineering from the University of Florida, Gainesville, FL, USA in 2011. She then worked as a postdoctoral researcher at the materials science department of University of Florida, and as a lecturer at the Middle East Technical University Northern Cyprus Campus. Currently, Dr. Yuksel is an assistant professor at the Hacettepe University, Department of Electrical and Electronics Engineering. She is also the director of the Pattern Recognition and Remote Sensing Laboratory (PARRSLAB http://parrslab.ee.hacettepe.edu.tr), where she is doing research on machine learning and computer vision with applications in defense and medical industry. Her latest projects include fusion of hyperspectral and LiDAR data, target detection from ground penetrating radar data, landmine, explosives and substance detection from hyperspectral and thermal images. Her lab is always open to collaborators, talented graduate as well as undergraduate students.
