Target detection in SAR images based on region growing

Abstract

An effective approach of target extraction based on regional growth and characteristic of speckle in Synthetic Aperture Radar (SAR) images was proposed. In point of characteristic of target in SAR images, the approach fully discussed the key problem (seed selection and homogeneity criterion in regional growth). Then, the corresponding decision and the process of target extraction were given. Simulated result indicates that the algorithm is not only noise-resistant in extracting target in SAR images, but also promising.
