Color Image Restoration Using Nonlocal Mumford-Shah Regularizers
We introduce several color image restoration algorithms based on the Mumford-Shah model and nonlocal image information. The standard Ambrosio-Tortorelli and Shah models are defined to work in a small local neighborhood, which are sufficient to denoise smooth regions with sharp boundaries. However, textures are not local in nature and require semi-local/non-local information to be denoised effic...
متن کاملMumford and Shah Model and Its Applications to Image Segmentation and Image Restoration
We present in this chapter an overview of the Mumford and Shah model for image segmentation. We discuss its various formulations, some of its properties, the mathematical framework, and several approximations. We also present numerical algorithms and segmentation results using the Ambrosio–Tortorelli phase-field approximations on one hand, and using the level set formulations on the other hand....
متن کاملA Mumford-Shah Level-Set Approach for Geometric Image Registration
A new, fully automated method for non-rigid registration of multimodal images is presented. Due to the large interdependance of segmentation and registration, the approach is based on simultaneous segmentation and edge-alignment. The two processes are directly coupled and thus benefits from using complementary information of the entire underlying dataset. It is formulated as a variational joint...
متن کاملA Multiscale Algorithm for Mumford-Shah Image Segmentation
We propose a new multiscale procedure for image segmentation that is based on the algorithm introduced by Song and Chan in [11]. After pointing out the presence of spurious stationary states for the original algorithm on certain types of images, we explain how the proposed procedure abates this issue and leads to a faster segmentation method.
متن کاملImage partition and video segmentation using the Mumford - Shah functional
The aim of this Thesis is to present an image partition and video segmentation procedure, based on the minimization of a modified version of Mumford-Shah functional. Generally, in most image processing applications, an image is usually viewed as a set of pixels placed on a rectangular grid. A single pixel provides an extremely local information making impossible any kind of interpretation. The ...
