Abstract

In this paper, we propose the speckle removal algorithm from Synthetic Aperture Radar (SAR) images via a segmentation technique based on Öztürk algorithm. The Öztürk´s algorithm is used to determine the distribution for each sample. These procedures are processed to see the relation between distribution of each pixels and segments of the image. We demonstrated the effectiveness of our algorithm by filtering speckle from an SAR image on study areas. As a result, our algorithm is able to preserve the quality of edge areas while speckle noise in homogeneous areas are suppressed.
