ABSTRACT
The main idea of path-followed method is adopting different integral path, which meets condition that the phase ingredient integral is equal to zero following the closed path, in order to bypassing the residuals according to different strategy. The accuracy of unwrapping is decided by the integral path in this method, Branch-Cut, Region-Growing and Mask-Cut are the implementations in the light of different path selection (Fomaro & Pascazio & Sclurinzi 1997).
