Terahertz single pixel imaging based on a Nipkow disk [PDF]

open access: yes, 2012
We describe a terahertz single pixel imaging system based on a Nipkow disk. Nipkow disks have been used for fast scanning imaging systems since the first experimental television was invented in 1926.

Evaluating the Effects of Shadow Detection on QuickBird Image Classification and Spectroradiometric Restoration

open access: yesRemote Sensing, 2013
Shadows in high resolution imagery create significant problems for urban land cover classification and environmental application. We first investigated whether shadows were intrinsically different and hypothetically possible to separate from each other ...
