MAP–Based Framework for Segmentation of MR Brain Images Based on Visual Appearance and Prior Shape
Published in The MIDAS Journal
Published in The MIDAS Journal
We propose a new MAP-based technique for the unsupervised segmentation of different brain structures (white matter, gray matter, etc.) from T1-weighted MR brain images. In this paper, we follow a procedure like most conventional approaches, in which [...]

This document describes the derivation of the mixture models commonly used in the literature to describe the probabilistic nature of speckle: The Gaussian Mixture Model, the Rayleigh Mixture Model, the Gamma Mixture Model and the Generalized Gamma Mixture [...]

Minimally Interactive Knowledge-based Coronary Tracking in CTA using a Minimal Cost Path
Published in The MIDAS Journal
Published in The MIDAS Journal
An algorithm for minimally interactive coronary artery tracking is presented. Tracking ability and accuracy results are demonstrated on 16 images CTA images.
First, a region of interest is automatically selected and a denoising filter applied. Then, for each [...]
