Context: SAR images can be acquired all time (day and night and whatever the weather) which is a real advantage for tropical areas. Nevertheless the signal is affected by speckle noise which induces strong fluctuations. Edge detection in such situations is difficult and usually lead to variable false alarm rate.
Objective: This project is dedicated to edge detection on SAR images. The idea is to train a network on natural images with added speckle noise (for which a ground truth is available ), with or without transfer learning and evaluate its performance on simulated and real SAR images. Comparisons with usual gradient for SAR data  will also be led (code provided).
