1. A method of detecting a foreign fluid on water, the method comprising: recording raw image data of the water's surface using a polarimeter to obtain polarized images; performing corrections on the polarized images to form corrected images; computing IR and polarization data products from the corrected images; converting the IR and polarization data products to a multi-dimensional data set to form multi-dimensional imagery; applying contrast enhancement algorithms to multi-dimensional imagery to form enhanced contrast images; detecting foreign fluid on the water's surface from the enhanced contrast images.
