Superresolution enhancement for temporal hyperspectral-oriented data sets
Jonathan Cheung-Wai Chan, Jianglin Ma, Frank Canters · 2009
Iterative backprojection superresolution (SR) image enhancement was applied to single-date and multi-date hyperspectral CHRIS imagery. SR enhanced imagery provides substantial increase in image detail and better characterization of image objects, in particular man-made objects such as buildings and roads. In terms of increase in signal to noise ratio, bi-temporal input produces only marginally better results than single-date input. However, better contrast in transition zones of rural habitat types is observed with the former. SR enhanced CHRIS imagery could potentially broaden the scope of application of this type of hyperspectral-oriented image data.
