TLDR

▪ 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

Clinical validation and assessment of a modular fluorescent imaging system and algorithm for rapid detection and quantification of dental plaque.
TL;DR: A proof of concept validation was provided for the construction and application of a sensitive cost-effective plaque-detecting device and the associated computer vision algorithm successfully captured red fluorescence signatures associated with dental plaque.

Statistical, Morphometric, Anatomical Shape Model (Atlas) of Calcaneus
TL;DR: The proposed for the first time statistical shape model of the calcaneus could be of value in many orthopaedic applications including providing support in diagnosing pathological lesions, pre-operative planning, classification and treatment of calcaneu fractures as well as for the development of future implant procedures.

K mean clustering based automated segmentation of overlapping cell nuclei in pleural effusion cytology images
TL;DR: The algorithm for automated segmentation of cell nuclei in pleural effusion cytology images which contain touching and overlapping cells is presented and the results are evaluated on the local dataset containing 35 images of cytology Pleural effusions with normal benign and cancer cells.

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.
