Abstract

A system and method of processing data associated with an array of pixels arranged in two dimensions are disclosed. The data includes a value representative of an intensity of photoexposure in one of a plurality of distinct spectral regions for each pixel location in the array. For at least one pixel location being associated with a first one of the plurality of spectral regions, a direction for interpolation is selected based upon an intensity gradient at the pixel location and an intensity continuity bias representative of a trend in changes in intensity in a neighborhood in the array of pixels about the pixel location. An interpolation among values representative of an intensity of photoexposure at two or more neighboring pixel locations in at least one set of neighboring pixels aligned along the selected direction to provides a value associated with the at least one pixel location which is representative of an intensity in a second one of the plurality of spectral regions distinct from the first spectral region.
