An electrostatic deformable model for medical image segmentation

A new deformable model, the charged fluid model (CFM), that uses the simulation of charged elements was used to segment medical images. Poisson's equation was used to guide the evolution of the CFM in two steps. In the first step, the elements of the charged fluid were distributed along the propagating interface until electrostatic equilibrium was achieved. In the second step, the propagating f...

Deformable Model for Image Segmentation

This paper presents an approach for image segmentation using Minimum Description Length (MDL) principle and integrating region growing, region boundary fitting, model selection in an integrated manner, on which the final result is a kind of compromise of various sources of knowledge such as the original grey level image and deformable object models. The deformable model is a closed polygon depi...

A Novel Deformable Model for Medical US Image Segmentation

Medical ultrasound (US) images are characterized by inherent noise perturbations which introduce uncertainty in their interpretation even by experienced radiologists. In this paper we propose a novel deformable model for medical US image segmentation, which incorporates a combination of domain and boundary integrals for the alleviation of the noise effects. It can be applied as a diagnostic aid...

An Unsupervised Learning Model for Deformable Medical Image Registration

We present an efficient learning-based algorithm for deformable, pairwise 3D medical image registration. Current registration methods optimize an energy function independently for each pair of images, which can be timeconsuming for large data. We define registration as a parametric function, and optimize its parameters given a set of images from a collection of interest. Given a new pair of sca...

Octree Grid Topology Preserving Geometric Deformable Model for Three-Dimensional Medical Image Segmentation

Topology-preserving geometric deformable models (TGDMs) are used to segment objects that have a known topology. Their accuracy is inherently limited, however, by the resolution of the underlying computational grid. Although this can be overcome by using fine-resolution grids, both the computational cost and the size of the resulting surface increase dramatically. In order to maintain computatio...
