A hyperspectral approach to color complexity

In the color cognition process of a scene, there is no use of the atmosphere, surface reflectance and illuminant interaction. Therefore, the color perception is blind. The color perception in human brain is directly related to the response of retinal photodetector tissues. Are there only three detectors in the retina; Red, Green, Blue detectors; or are there many? Is spectral band clustering related to color perception? These are some of the questions we like to address. In this study, hierarchical band clustering is applied to the scenes obtained with visible band hyperpsectral cameras and tentative approach is proposed for color complexity.
