Abstract:
A method for adaptive spectral image capture that may be performed via an image capture device is disclosed. A default capture parameter is applied to an imaging assembly and a sample image of a scene is captured by an image capture device. The sample image is analyzed to identify transition zones between multiple different regions. An initial guess as to which spectral regions a filter mode might work best is obtained based on dominant transition region spectrum and a first iterated step in which numerical values for the filter mode are calculated. A second iterated step in which each such filter mode is evaluated for effectiveness against other filter modes. The regions in which a specific filter mode works best becomes associated with the filer mode and these regions become the guess for the next iteration.
