Auto-kNN: Brain Tissue Segmentation using Automatically Trained k-Nearest-Neighbor Classification
No opinion
In this paper we applied one of our regularly used processing pipelines for fully automated brain tissue segmentation. Brain tissue was segmented in cerebrospinal fluid (CSF), gray matter (GM) and white matter (WM). Our algorithms for skull stripping, tissue [...]

Non-negative matrix factorization framework for dimensionality reduction and unsupervised clustering
No opinion
Non-negative Matrix Factorization (NMF) is a robust approach to learning spatially localized parts-based subspace patterns in applications such as document analysis, image interpretation, and gene expression analysis. NMF-based decomposition capabilities are [...]

Minimally Interactive Knowledge-based Coronary Tracking in CTA using a Minimal Cost Path
No opinion
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 [...]
