Extraction of structural features on SAR images: an adaptive version of the HK-Filter

The HK-filter previously developed by the authors is a statistical filter devoted to the speckle removal and structural features enhancement on SAR images. As this filter is based on a pattern analysis applied to the shape observed in a given neighborhood and according to a gray- level range, it can be used to extract structural features. We purpose here to use spatial arrangement given by the occurrence of the constitutive elements of shapes, to extract and to differentiate the different structural features encountered on SAR images.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
