Remote sensors capture large scenes that are conventionally split in smaller patches before being stored and analyzed. Traditionally, this has been done by dividing the scene in rectangular windows. Such windowing methodology could provoke the separation of spectrally homogeneous areas or objects of interest into two or more patches. This is due to the presence of objects of interest in correspondence...
Remotely sensed hyperspectral imaging is a technique that generates hundreds of spectral bands at different wavelength channels for the same area on the surface of the Earth. Computationally effective processing of these image cubes can be greatly beneficial in many application domains, including environmental modeling, risk/hazard prevention and response, or defense/security. With the aim of providing...
Due to the large data volumes often associated with multichannel imagery in many application domains, including satellite imaging and aerial reconnaissance, there is a clear need for parallel algorithms able to process these high-dimensional data sets quickly enough for practical use. This paper describes a parallel implementation of a multichannel classification algorithm that naturally combines...
This paper explains some of the the goals and objectives of the newly started HYPER-I-NET Marie Curie Research and Training Network. In particular, the requirements related to the definition and implementation of an efficient, adequate and sufficiently general data processing chain for hyperspectral data analysis are considered. Some of the research lines that are expected to play a central role in...
Spectroscopy has existed for more than three centuries now. Nonetheless, significant scientific advances have been achieved. We discuss the history of spectroscopy in relation to emerging technologies and applications. Advanced focal plane arrays, optical design, and intelligent on-board logic are prime prospective technologies. Scalable approaches in pre-processing of imaging spectrometer data will...
Advances in space and computer technologies are revolutionizing the way remotely sensed data is collected, managed and interpreted. The development of efficient techniques for transforming the massive amount of collected data into scientific understanding is critical for space-based Earth science and planetary exploration. Although most currently available parallel processing strategies for hyperspectral...
