Abstract :
A region growing algorithm for InSAR phase unwrapping is presented. Initial experiments show that the region growing phase unwrapping algorithm can handle SAR interferograms which are more noisy than other unwrapping algorithms can handle. This algorithm also allows dense fringes caused by steep topography
