The colour of a light beam is based on the reading of severel photodetectors with different spectral responses and metamerism results when a set of photodetectors is unable to resolve two spectra. The spectra are then said to be metameric. We are interested in exploring the concept of metamerism in the tetrachromatic case. Applications are in computer vision, computational photography and satellite imaginery, for example.enPhotodetectorComputer sciencePhotographyOpticsSpectral lineLight beamArtificial intelligenceComputer graphics (images)article
