Abstract: Hyperspectral data are usually generated by using sensors installed on airplanes, such as those used by NASA, known as the Airborne Visible \ Infrared Imaging Spectrometer (AVIRIS), or by using special satellites.
Hyperspectral images are therefore a multidimensional collection of information coming from the electromagnetic spectrum of the observed object. These sensors, through the observation of an object, are able to capture a large portion of the object’s electromagnetic spectrum.
Given that any object has an unambiguous fingerprint on the electromagnetic spectrum, hyperspectral data allows the identification of different types of materials: for example, the spectral signature of oil can help mineralogists to find new oil wells.
Hyperspectral data need to be efficiently compressed to be stored and / or transmitted.
In this talk we will discuss the compression of hyperspectral images and the new recent advances in this field.
Brief Biography of the Speaker:
Bruno Carpentieri received the “Laurea” degree in Computer Science from the University of Salerno, Salerno, Italy, and the M.A. and Ph.D. degrees in Computer Science from the Brandeis University, Waltham, MA, U.S.A.
Since 1991, he has been first Assistant Professor and then Associate Professor of Computer Science at the University of Salerno (Italy).
His research interests include lossless and lossy image compression, video compression and motion estimation, information hiding.
He has been, from 2002 to 2008, Associate Editor of the journal IEEE Trans. on Image Processing, he was chair and organizer of the International Conference on Data Compression, Communication and Processing 2011, co-chair of the International Conference on Compression and Complexity of Sequences, and, for many years, program committee member of the IEEE Data Compression Conference. He has been chair of the CCP2011 Conference. He has been responsible for various European Commission contracts regarding image and video compression.
