PhaseDerivativeVariance creates a phase quality map by computing the variance of the partial derivatives of the locally unwrapped phase. This is then used to guide the phase unwrapping path. Uses only the 4 nearest neighbours. The user may also input a binary mask. function derivative_variance = PhaseDerivativeVariance (IM_phase, varargin) Created by BS Spottiswoode on 18/10/2004 Last modified on 06/12/2004 2010/07/19 Carey smith Corrected a bug on the line before computing dy (dimx, :)
