The Effect Of Speckle On The Segmentation Of Synthetic Aperture Radar Images
Jong-Sen Lee, Igor Jurkevich · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1988
The presence of speckle in Synthetic Aperture Radar (SAR) images makes segmentation of such images difficult either by gray levels or by texture. A natural way to segment an image by gray level is to select thresholds at the valleys of its multi-modal histogram if it exists. This paper will investigate the existence of histogram valleys in SAR images, the classification errors and devise a procedure for multi-level thresholding of SAR images.
