Correction of intensity inhomogeneity in SAR images via variational approach
Bin Xiao, Yaxin Peng · 2013
Intensity inhomogeneity is sometimes visible in Synthetic Aperture Radar (SAR) images. A number of techniques have been devised to correct this defect, most of which need certain parameters, such as incidence angle at each point or the Doppler centroid. In this paper we propose a unified method for bias correction using a variational approach in which no physical parameter is needed.
