I am trying to make a graph to ID oil slicks.

I’ve used multiple different S1a images for Refrugio (Oil spill last year), tried SLC and GRDH - two examples:
Also I got some ENVISAT SAR images from a tutorial of the Deepwater Spill so a large oil slick. These are lower fileszes so easier to test with.
I’ve tried experimenting with the background window size in the oil detection and the threshold shift - ive also changed the minimum oil cluster size. For example here using the smaller ENVISAT file i have:
background window = 61
Threshold shift = 2.0
minimum cluster size = 0.1
but all i seem to get is a few oil points being ID’d when i look at the .Should this be a polygon?
Should this be a polygon? Any suggestions what i am doing wrong?
Thanks in advance,
