Diffusion-based Regularisation Strategies for Variational Level Set Segmentation

چکیده
As already indicated in (2), the recipe described above implicitly assumes that V = L2. Therefore it is mathematically correct to refer to ∇E as the L2-gradient and not simply the gradient. Unfortunately, the L2-gradient is, to put it simply, too local and therefore prone to lead into an undesired local minimum as pointed out by Charpiat et al. [2] as well as Sundaramoorthi et al. [3]. Thus regularisation strategies are necessary to avoid these undesired local minima.

Tensor Field Regularisation for DT-MR Images
We present here a method to regularise diffusion tensor magnetic resonance images. The scheme is divided in two steps: a restoration of the principal diffusion direction (PDD) field, and a regularisation of the eigenvalue maps. The first step is based on a recent variational approach to restore direction maps, and the second step consists of an anisotropic diffusion scheme driven by the restore...
متن کاملVariational data assimilation via sparse regularisation
This paper studies the role of sparse regularisation in a properly chosen basis for variational data assimilation (VDA) problems. Specifically, it focuses on data assimilation of noisy and down-sampled observations while the state variable of interest exhibits sparsity in the real or transform domains. We show that in the presence of sparsity, the ‘1-norm regularisation produces more accurate a...
متن کاملA Hybrid Method for Segmentation and Visualization of Teeth in Multi-Slice CT scan Images
Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...
متن کاملWeighted Procrustes Analysis for Diffusion Tensor Imaging
There has been substantial interest in the development of methods for processing diffusion tensor fields, taking into account the non-Euclidean nature of the tensor space. In this paper, we generalise Procrustes analysis to weighted Procrustes analysis for diffusion tensor smoothing, interpolation, regularisation and segmentation in which an arbitrary number of tensors can be processed efficien...
متن کاملMultiple Motion and Occlusion Segmentation with a Multiphase Level Set Method
In this paper, we propose a new variational formulation for simultaneous multiple motion segmentation and occlusion detection in an image sequence. For the representation of segmented regions, we use the multiphase level set method proposed by Vese and Chan. This method allows an efficient representation of up to 2 regions with L level-set functions. Moreover, by construction, it enforces a dom...
