On Level-Set Type Methods for Recovering Piecewise Constant Solutions of Ill-Posed Problemswn level sets and unknown level values. A level set framework is established for the inverse problem and a Tikhonov regularization approach is proposed. Existence of generalized minimizers for the Tikhonov functional is proven. Moreover, we establish convergence and stability results, characterizing

The Nonlinear Tensor Diffusion in Segmentation of Meaningful Biological Structures from Image Sequen of nonlinear tensor diffusion image smoothing and subjective surface based image segmentation. Since the fine cell structure would restrain the evolving segmentation function to achieve a shape of meaningful biological structures, we have to smooth properly the images in the sequence. To that goal

Composed Segmentation of Tubular Structures by an Anisotropic PDE Modellt according to specific logic combinations. The approach and the segmentation model are general but we apply the C-segmentation technique to the challenging problem of segmenting tubular-like structures. The reconstruction is obtained by continuously deforming an initial distance function following

Extrapolation of Vector Fields Using the Infinity Laplacian and with Applications to Image Segmentat edge map of a given image and allowing to increase the capture range. Contrary to prior related works, we reduce the number of unknowns to a single one . by assuming that the expected vector field is the gradient field of a scalar function. The model is phrased in terms of a functional minimization

Momentum Based Optimization Methods for Level Set Segmentationther image derived terms. The solution of the segmentation problem is the contour which extremizes this functional. The standard way of solving this optimization problem is by gradient descent search in the solution space, which typically suffers from many unwanted local optima and poor convergence.

Geodesically Linked Active Contours: Evolution Strategy Based on Minimal Pathsally linked active contour model consists in a set of vertices connected by paths of minimal cost. This makes up a closed piecewise defined curve, over which an edge or region energy functional is formulated. The greedy algorithm is used to move vertices towards a configuration minimizing the energy
