Abstract
The disclosure concerns processing of electronic images, such as hyperspectral or multispectral images (302) to determine an output color value for a component spectrum of a decomposed multispectral or hyperspectral image. A processor (120) first determines or accesses the component spectrum and a first color value for the component spectrum and receives an input color value for a pixel location in the image, wherein the component spectrum contributes to the pixel. The processor (120) then determines the output color value for the component spectrum based on the first color value for the component spectrum, the input color value and a utility score and stores the output color value for the component spectrum on a datastore (118). It is an advantage that the processor (120) receives a color value for a pixel location but the output color value is not exactly the received color value but one that is determined based on a utility score.
