Unsupervised and Adaptive Segmentation of Multispectral 3D Magnetic Resonance Images of Human Brain: A Generic Approach

This paper provides a generic algorithm for the segmentation of three dimensional multi-spectral magnetic resonance images. The algorithm is unsupervised and adaptive, does not require initialization, classifies the data in any number of tissue classes and suggests an optimal number of classes. It uses a statistical model including Bayesian distributions...

A Statistically Based Flow for Image Segmentation

This paper presents a new algorithm for 3D medical image segmentation. The algorithm is versatile, fast, relatively simple to implement, and semi-automatic. It is based on minimizing a global energy defined from a learned non-parametric estimation of the statistics of the region to be segmented. Implementation details are discussed and...

Simultaneous Truth and Performance Level Estimation (STAPLE): An Algorithm for the Validation of Image Segmentation

Characterizing the performance of image segmentation approaches has been a persistent challenge. Performance analysis is important since segmentation algorithms often have limited accuracy and precision. Interactive drawing of the desired segmentation by human raters has often been the only acceptable approach, and yet suffers from intra-rater and inter-rater variability. Automated...

Three Validation Metrics for Automated Probabilistic Image Segmentation of Brain Tumors

The validity of brain tumor segmentation is an important issue in image processing because it has a direct impact on surgical planning. This paper examines the segmentation accuracy based on three two sample validation metrics against the estimated composite latent gold standard, which was derived from several experts' manual segmentations...

Statistical Validation of Automated Probabilistic Segmentation Against Composite Latent Expert Ground Truth in MR Imaging of Brain Tumors

The validity of segmentation is an important issue in image processing because it has a direct impact on surgical planning. Binary manual segmentation is not only time-consuming but also lacks the ability of differentiating subtle intensity variations among voxels, particularly for those on the border of a tumor and for...

Validation of Image Segmentation and Expert Quality With an Expectation-Maximization Algorithm

Characterizing the performance of image segmentation approaches has been a persistent challenge. Performance analysis is important since segmentation algorithms often have limited accuracy and precision. Interactive drawing of the desired segmentation by domain experts has often been the only acceptable approach, and yet suffers from intra-expert and inter-expert variability. Automated...
