Oil Slick Detection Filter
Detection 1 SAR images.
Oil Slick Detection Filter detects oil slicks on the sea with SAR images from Sentinel-1.
This filter can distinguish between oil slicks and other sea surfaces with high accuracy, which is difficult to detect by non-specialists.
By using the difference in radio wave reflection characteristics of the water surface, the algorithm automatically detects oil slick from a single SAR image. This block uses a deep learning algorithm to achieve overwhelming performances.
