Design goals and solutions for display of hyperspectral images
Design goals and solutions are proposed for the display of hyperspectral imagery on tristimulus displays. The requirements of a hyperspectral visualization depend on the task. We focus on creating consistent representations of hyperspectral data that can facilitate understanding and analysis of hyperspectral scenes, and may be used in conjunction with task-specific visualizations. Fixed linear spectral weighting envelopes are given which create natural looking imagery where hue, brightness, saturation and white-point have meanings consistent with the human visual system interpretation of natural scenes. For AVIRIS images, hue interpretation of water and vegetation is also preserved. The proposed designs avoid the pre-attentive distractions of PCA imagery, and provide comparable spectral and edge discriminability.
