Title:Mixture Models based Variational Image Segmentation, Restoration and Some Applications


Abstract:In this talk, we will integrate mixture models (statistics) and regularization technique (PDE) to develop several algorithms for image segmentation and restoration. Some new adaptive fidelity terms and nonlocal regularizers will be introduced by analyzing a well-known expectation maximization process. The well-posedness theory for the proposed methods will be discussed. We will give some examples of the applications for the proposed methods.
