This paper describes a collaborative collection campaign to spectrally image and measure a well characterized scene for hyperspectral algorithm development and validation/verification of scene simulation models (DIRSIG). The RIT Megascene, located in the northeast corner of Monroe County near Rochester, New York, has been modeled and characterized under the(More)
Thermal infrared (TIR) imagery generated by midwave (3to 5-pm) and longwave (8to 14-pm) sensors is being increasingly used for a variety of remote sensing applications. Some of this interest is motivated by the temperature information encoded in these images, whereas other interest is driven by the need for high-resolution sensors with day and night(More)
This work describes the water collection experiment component of the Megacollect 2004 campaign. Megacollect was a collaborative campaign coordinated by RIT with several institutions to spectrally measure various target/background scenarios with airborne sensors and ground instruments. An extension to the terrestrial campaign was an effort to simultaneously(More)
This study investigates small aerosol particles as a source of an imaging phenomenon observed in thermal remote sensing data. The phenomenon is characterized by degraded atmospheric transmissions in the thermal infrared while high transmissions (clear conditions) are observed in the visible wavelength region. This atmospheric anomaly has been linked to(More)
This paper describes a concept for using physics based models to support exploitation of remotely sensed image spectrometer data. It then reviews several methods from the literature illustrating more specifically how physics based models have been used as part of atmospheric correction, water quality assessment and temperature measurement algorithms.(More)
Image intensifying cameras have been found to be extremely useful in low-light-level (LLL) scenarios including military night vision and civilian rescue operations. These sensors utilize the available visible region photons and an amplification process to produce high contrast imagery. It has been demonstrated that processing techniques can further enhance(More)
Case Studies: • Developed by University of Wisconsin • OPPORTUNISTIC SCHEDULING Only seeks idle workstations. • DISTRIBUTION OF JOBS ACROSS FLOCKS (Workstation Group) Assignment of jobs to other idle workstations. • JOB MIGRATION Includes transfer of in-progress jobs (preempted due to user activity) from one workstation to(More)
A model is presented for generation of synthetic images representing what an airborne or satellite thermal infrared imaging sensor would record. The scene and theatmosphere are modeled spectrally with final bandwidth determined by integration over thespectral bandwidth of the sensor (the model will function from 0.25 -20 tm). The scene is created using a(More)
