A deep deformable residual learning network for SAR image segmentation

Reliable automatic target segmentation in Synthetic Aperture Radar (SAR) imagery has played an important role in the SAR fields. Different from the traditional methods, Spectral Residual (SR) and CFAR detector, with the recent advancements in machine learning theory, new methods based on machine learning show better performance in SAR target segmentation. In this paper, we proposed a deep deformable residual learning network for target segmentation, which attempts to preserve the precise contour of the target. The deformable convolutional layers and residual learning block are applied in this technique, which could extract and preserve the geometric information of the target as much as possible. The proposed method is evaluated based on the Moving and Stationary Target Acquisition and Recognition (MSTAR) dataset, and the experimental results have shown the superiority of the proposed network for the precise segmentation of the target.
