Claim Text:
1. A method of detecting a foreign fluid on water, the method comprising: estimating an expected polarization response for a foreign fluid desired to be detected; determining, from the estimated expected polarization response, an optimal position of a polarimeter to take images of the water's surface; positioning the polarimeter at the optimal position for taking images of the water's surface; recording raw image data of the water's surface using the polarimeter to obtain polarized images of the area; 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; automatically detecting foreign fluid on the water's surface from the enhanced contrast images.
