Abstract

The rise of deep learning has impacted profoundly all aspects of image processing and remote sensing. Following this trend, in the last few years, a large number of data-driven methods have been proposed also for SAR image despeckling. However, in spite of this large effort, only limited performance gains have been observed. We believe this is mostly due to the use of training sets that are only partially fit to the task, and sometimes plain wrong. In this work we assess experimentally the impact of training set design on the performance of SAR image despeckling with the goal of highlighting solid guidelines for sensible training.
