New technologies for improving spatial resolution of satellite images

In this paper, the results of different image fusion schemes for pixel level fusion and image super-resolution reconstruction algorithm are presented. A new method that performs enhancements in the spatial resolution is employed. It has the following unique features: (a) higher ability of improving image spatial resolution (b) increased reduction of pixel uncertainties due to calibration errors through a new adaptive filtering technique, and (c) improved reduction of the blurring through a new blur estimation and super-resolution restoration that employs cross-validation for regularization. Tradeoff studies with other state of the art spatial resolution enhancement algorithms are presented.
