1. A method for adaptive spectral image capture using an image capture device which includes an imaging assembly having a spectral response which is tunable in accordance with a capture parameter, the method comprising: applying a default capture parameter to the imaging assembly, wherein the default capture parameter has high spectral dimensionality; capturing a sample image of a scene; analyzing the sample image to identify transition zones between multiple different regions in the scene, wherein each of such multiple different regions shares similar spectral content that is dissimilar from spectral content in adjacent ones of the multiple different regions; adjusting a spectral sensitivity of the imaging acquisition system for each region and determining the appropriate capture parameter to be applied to the imaging assembly applying the capture parameter to the imaging assembly; and capturing and storing a spectral image of the scene.
