Freeman´s decomposition model based new spill detector

In this paper, a new parameter called Bragg energy proportion is introduced for spill oil detection, based on Freeman decomposition model. Bragg energy proportion is small in spill region and it is large in sea clutter region or Oleyl Alcohol (OLA) region. So, this parameter can be used to detect oil spill from sea clutter and meanwhile it reduces the OLA false-alarm effectively. In addition, the parameter is derived by HHVV dual-polarized SAR data. Using C band SIR-C SAR data, the authors demonstrate the effectiveness of the proposed method.
