1. A method for processing an image, comprising: receiving a sample set of data generated by transforming and sampling an optical property of an original color image in a spatial basis, wherein the transformation effected is substantially local in the spatial basis and is 85-Capture or greater; and applying a generalized inverse of said transform to the sample set of data to produce a set of inferred original image data, wherein the generalized inverse does not use variational minimization and does not use color ratios.
