A region-cutting phase unwrapping algorithm based on SVM （Support Vector Machines） is proposed, and every pixel can be classified using the phase-related information including residue and phase derivate variance, thus the intetferogram is cut into high-quality non-mask region and low-quality mask region. Region-growing strategy is applied to unwrap mask region after the non-mask region is unwrapped by modified ltoh method, The experiment result on real and simulated SAR interferogram shows the proposed algorithm is more effec...
