Edge Attention Superpixel Segmentation for Polarimetric SAR Images

In this paper, we propose an edge attention superpixel segmentation method for polarimetric synthetic aperture radar (PolSAR) images. Image edges are specially considered during the segmentation process by imposing an edge-attention-based distance. The edge-attention-based distance is defined on an edge map and it ensure that one superpixel is not divided into several parts by image edges, which helps to generate superpixels with better boundary adherence. Experimental results on AirSAR and Radarsat-2 images demonstrate the superiority of the proposed method.
