Claim One:
1. A method of reducing bandwidth of a multichannel image that has multiple channels each representing a respective spectral component of a scene, the method comprising the steps of: A. identifying a calibration location in a multichannel training image; B. determining a contrast within each channel of the multichannel training image at a location corresponding to the calibration location; C. determining a weighting factor for each channel of the multichannel training image as a function of the contrast within the channel at the location corresponding to the calibration location; and D. generating, from a multichannel runtime image, a first reduced bandwidth runtime image but that has fewer channels than the multichannel runtime image, the reduced bandwidth runtime image being generated as a first function of (i) the multichannel runtime image, and (ii) the weighting factors for the channels of the multichannel training image.
