Abstract
▪ 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.

Oversegmentation reduction in watershed-based grey-level image segmentation

TL;DR: In this paper, the watershed transformation is used to partition the image into homogeneous regions, and then the successive assignment of the regions to either the foreground or the background is performed.

Robust Active Contour Model Using Patch-Based Signed Pressure Force and Optimized Fractional-Order Edge

TL;DR: Wang et al. as mentioned in this paper proposed an active contour model (ACM) consisting of a local fitting term, an edge-based term and an external force term for image segmentation.

Automatic Spine Segmentation using Convolutional Neural Network via Redundant Generation of Class Labels for 3D Spine Modeling.

TL;DR: A fully automatic approach for spine segmentation from CT based on a hybrid method that combines the convolutional neural network (CNN) and fully Convolutional network (FCN) and utilizes class redundancy as a soft constraint to greatly improve the segmentation results.

Stochastic Relaxation, Gibbs Distributions, and the Bayesian Restoration of Images

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.
