Abstract :
The authors investigate the problem of generating weight masks to be used in conjunction with the minimum cost flow algorithm for InSAR phase unwrapping. Different weight values are automatically assigned to the interferogram pixels through a classification of several features extracted from the dataset. Examples on simulated images show that the approach gives good results, and confirm that less error is committed as more information is taken into account in generating the weights
