Speckle filtering is often carried out to improve the interpretation of polarimetric synthetic aperture radar (PolSAR) data for terrain classification, retrieval of physical scattering properties etc. As inspired by Newton's law of universal gravitat

This paper examines two test statistics, namely, likelihood ratio statistic and Roy's largest eigenvalue, for detecting changes in multi-look bi-temporal ALOS-2 PALSAR-2 fully polarimetric data. The latter turns into the well-known intensity ratio wh

A multi-stage four-component decomposition, which is inspired by the generalized odd-bounce and double-bounce scattering models, is presented in this paper for reducing negative power pixels. Its performance was evaluated by using NASA/JPL AIRSAR Pol

Absolution radiometric calibration is the process of obtaining the relation between the at-sensor radiance and the pixel digital number recorded by the sensor. It is important to be able to calculate the radiance for every pixel in a satellite imager

The characteristics of sub-pixel fires in Suomi-NPP VIIRS data are studied using the Nightfire algorithm which attempts to fit the spectral radiance to a blackbody function. For small and/or low intensity fires, the fire temperature tends to be under

Extraction of 3D building information from high resolution satellite imagery is generally carried out manually. Automatic algorithms to extract such information are highly desirable, but have so far met with limited success. Previously, we reported a
