3. RESULTS AND CONCLUSIONS 
e The PU method significantly reduces the overall 
processing complexity and is making analysis easier and 
more robust for the user. 
e The PU method provides a quick and practical operational 
method for selecting ROIs, without using statistical 
classification algorithm, where MNF function and 2-D 
scatter plot are available in all image analysis software 
packages. 
The results indicated good separation of oil slicks, oiled water, 
and polluted water. Results are used as a preliminary 
identification of oil targets, as there is no ground truth data 
available. PU provides a method of resolving only that fraction 
of the data division problem that directly relates to the specific 
goals of the investigation. PU allowed mapping of the apparent 
target abundances in the presence of an arbitrary and unknown 
spectrally mixed background.
