Oil detection algorithm based on edge detection
Siyuan Wang · National Remote Sensing Bulletin · 2009
The side-look imaging of SAR (Synthetic Aperture Radar) may result in the pockety density, so we can not get a satisfying result by using CFAR (constant false alarm rate) detection on the whole image. To improve the oil detection capability, we propose a new oil detection method based on edge detection in this paper. First, the AOI (area of interest) of oil is detected through radio edge detection, then an improved Weibull-CFAR detector is applied to the AOI. Comparing with the whole CFAR detection results, this detection method demonstrates better accuracy and efficiency on SAR images with pockety density, especially suitable for the oil detection of big images.
