ABSTRACT:
The present invention discloses a super resolution pan-sharpening technique that is used to increase the resolution of a multi-spectral signal using a panchromatic signal. Typically, multi-spectral signals, i.e., signals that contain a defined spectral band, have lower resolution than panchromatic signals since the multi-spectral signals normally contain fewer photons and require larger detectors for similar exposure periods. The technique of the present invention utilizes the panchromatic signal to increase the resolution of the multi-spectral signals to provide an increased resolution color output. The resolution of other spectral signals, such as infrared signals and UV signals, or any other desired signal, can also be increased in accordance with the techniques of the present invention.
