in reference [21], a multicentric loss function was used to ensure better agreement with the actual
statistics of real SAR data. In addition to the L2 distance between the reectivity of the estimated
and reference images, their gradient, to ensure edge preserving, and the KS distance between pdf of
noise, to ensure the statistics of the real SAR data, are also used.
2.3.2.3.2 Self- Supervised Learning Techniques
Self- supervised learning techniques point to another learning strategy to avoid the limitations
mentioned in supervised techniques. For the self- supervised learning techniques, learning is
performed only with noisy images, without the need for noise- free reference images. ...
