Abstract: One embodiment of the present invention sets forth a technique for lossless compression of color data. Color data for a packet including multiple sub-pixel samples is compressed using a predictor map that is selected based on the sampling format specified for the graphics surface storing the color data.

The difference samples are truncated and tested to determine if the difference samples can fit into one or more compressed data formats, i.e., if the color data can be compressed without loss. When compression can be performed without loss, the transformed packet is output. Otherwise, the original packet is output.

Abstract: The disclosure concerns processing of electronic images, such as hyperspectral or multispectral images. In particular, but is not limited to methods, software and computer systems for determining underlying spectra of an image of a scene. The image data comprises for each pixel location a sampled image spectrum that is a mixture of plural reflectance spectra. Processor 310 determines or accesses plural hyperplanes that each have plural linearly independent basis vectors. Each hyperplane represents an estimate of one of the plural reflectance spectra. The processor 310 then determines for each pixel location, a contribution of the plural basis vectors of each hyperplane to the image spectrum of that pixel location. The processor 310 determines or accesses plural hyperplanes and not plural endmembers directly. Hyperplanes are two-dimensional while endmembers are only one-dimensional. As a result, hyperplanes carry more information, such as the illumination spectrum and are therefore of greater use.
