Abstract :
We present an anisotropic diffusion equation designed to restore interferometric images. It has two main purposes, the first is to preserve the structures and discontinuities formed by the fringes. The second is to incorporate the noise modeling which is specific to this kind of images. Besides we show that our model formalizes previous related work in interferometry filtering.
