Abstract:
A system () for processing remotely acquired imagery is provided. The system () includes a storage element for receiving imagery data defining a first image of a panchromatic image type using a sensor characterized by a panchromatic spectral response curve and a second image of a multi-spectral image type using at least one other sensor characterized by a plurality of multi-spectral response curves associated with a plurality of optical bands. The first image has a first spatial resolution and a first spectral resolution. The second image has a second spatial resolution lower than the first spatial resolution and a second spectral resolution higher than that first spectral resolution. The system () also includes a processing element configured for deriving a radiation transfer model based on meta-data associated with one of the first and the second image and for determining a set of spectral weights for down-sampling the second image to the first spectral resolution based on the radiation transfer model and the panchromatic and the multi-spectral response curves.

Abstract:
A system for processing remotely acquired imagery includes a storage element () for receiving first and second sets of imagery data associated metadata defining a first image of a panchromatic image type and a second image of a multi-spectral image type (). The system also includes a processing element () communicatively coupled to the storage element and configured for obtaining a mapping between pixels in the first image and the second image based on the associated metadata (). The processing element is further configured for generating a third set of imagery data defining a third image of a panchromatic type based on the second set of imagery data (). The processing element is also configured for generating an alternate mapping for the first and second images based on comparing areas of pixels in the first and third images that are non-corresponding according to the mapping function ().

Abstract:
A method for processing remotely acquired imagery includes obtaining imagery data defining a first image of a panchromatic image type, the first image having a first spatial resolution, and obtaining imagery data defining a second image of a multi-spectral image type, the second image having a second spatial resolution lower than the first spatial resolution. The method also includes obtaining a mapping function specifying a position of pixels in the first image with respect to pixels in the second image and adapting the mapping function to a high common spatial resolution higher than the second spatial resolution. The method further includes generating a third set of imagery data defining a third image of a panchromatic type based on the first set of imagery data and the adapted mapping function and having the high common spatial resolution and adjusting the mapping function based on a first difference between the first and the third images at the high common spatial resolution.
