Abstract: We introduce a variational approach to wavelet denoising and phase unwrapping of interferometric SAR data using the Mumford-Shah framework. The Mumford-Shah variational framework can handle discontinuities in the scene besides unifying the phase unwrapping and denoising in one mathematical formalism.
