Abstract:
1. A method for processing remotely acquired imagery, comprising: receiving imagery data defining a first image associated with a first spectral band and a plurality of second images associated with a plurality of second spectral bands, said first image having a first spatial resolution, and each of said second images having a second spatial resolution lower than said first spatial resolution; obtaining a plurality of first reflectance functions, said plurality of first reflectance functions specifying reflectance values for pixels in each of said plurality of second images; generating a second reflectance function estimating reflectance values for pixels in said first image based on said plurality of first reflectance functions; obtaining a third reflectance function specifying reflectance values for pixels in said first image based on said second reflectance function, said imagery data for said first image, and at least one facet orientation constraint; modifying said plurality of first reflectance functions to generate a plurality of fourth reflectance functions specifying reflectance values for pixels in said plurality of second images, said modifying based on a difference between said second and said third reflectance functions; and computing imagery data defining a plurality of third images associated with said plurality of second spectral bands and having said first spatial resolution, said plurality of third images based on said plurality of fourth reflectance functions.
