Abstract :
A generic theoretical framework is discussed for using different types of prior knowledge in a phase unwrapping approach based on a Markov random field (MRF) formalism. This approach allows for the regularization of the phase unwrapping process by using various types of information such as thematic maps and can help to make results more robust to disturbing phenomena like statistical noise and aliasing than classical approaches
