Determining colour values in hyperspectral or multispectral images

Abstract

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