▪ Abstract Image segmentation plays a crucial role in many medical-imaging applications, by automating or facilitating the delineation of anatomical structures and other regions of interest. We present a critical appraisal of the current status of semiautomated and automated methods for the segmentation of anatomical medical images. Terminology and important issues in image segmentation are first presented. Current segmentation approaches are then reviewed with an emphasis on the advantages and disadvantages of these methods for medical imaging applications. We conclude with a discussion on the future of image segmentation methods in biomedical research.read more

TL;DR: A brief overview of several methods that may be considered to analyze objects’ movement, namely, for their segmentation, tracking and matching in images, and for estimation of the deformation involved between images.

Brain volume measurements in patients with human T-cell lymphotropic virus-1-associated tropical spastic paraparesis.

TL;DR: The authors conclude that reductions in BPF do not occur frequently in patients with HAM/TSP, and believe that one individual case of significant brain atrophy raises the question as to whether atrophy selectively targets the spinal cord of HAM/ TSP patients or may involve the brain as well.
An Affordable and Practical 3D Solution for the Aesthetic Evaluation of Breast Cancer Conservative Treatment
TL;DR: This work aims at producing a practical tool that is easy to use, based on a computational algorithm that performs 3D reconstructions from low-cost systems, namely: reconstruction algorithm from uncalibrated views, using an epipolar geometry approach and RGB-D sensors.

Comparison Of K- Means And Fuzzy C- Means Algorithms
Ankita Singh,Prerna Mahajan +1 more
TL;DR: Two fuzzy algorithms are compared: fuzzy c-means algorithm and fuzzy k means algorithm, which aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean.

Neural Networks: A Comprehensive Foundation
TL;DR: Thorough, well-organized, and completely up to date, this book examines all the important aspects of this emerging technology, including the learning process, back-propagation learning, radial-basis function networks, self-organizing systems, modular networks, temporal processing and neurodynamics, and VLSI implementation of neural networks.

Stochastic Relaxation, Gibbs Distributions, and the Bayesian Restoration of Images
Stuart Geman,Donald Geman +1 more
TL;DR: The analogy between images and statistical mechanics systems is made and the analogous operation under the posterior distribution yields the maximum a posteriori (MAP) estimate of the image given the degraded observations, creating a highly parallel ``relaxation'' algorithm for MAP estimation.
