Introducing contrast and luminance normalisation to improve the quality of subtractive resolution merge technique
Ashraf, Muhammad Salman; Brabyn, Lars; Hicks, Brendan J. (2013)Subtractive resolution merge (SRM) is a contemporary image fusion method that produces highly preserved spatial and spectral resolution. This method is limited to dual sensor platforms with specific band ratios between the ... -
Remote sensing of freshwater environments: Trial application on the lower Waikato River.
Ashraf, Muhammad Salman; Brabyn, Lars; Hicks, Brendan J. (Centre for Biodiversity and Ecology Research, The University of Waikato, 2009-06)The overall goal of the study is to evaluate multi-sensor and multi-spectral satellite data to characterise different freshwater habitat zones of large rivers and lakes of the Waikato region. The earlier evaluation of ... -
