Hippocampus Segmentation Based on Local Linear Mapping
We propose local linear mapping (LLM), a novel fusion framework for distance field (DF) to perform automatic hippocampus segmentation. A k-means cluster method is propose for constructing magnetic resonance (MR) and DF dictionaries. In LLM, we assume that the MR and DF samples are located on two nonlinear manifolds and the mapping from the MR manifold to the DF manifold is differentiable and lo...
متن کاملAutomated Hippocampal Subfield Segmentation at 7T MRI.
BACKGROUND AND PURPOSE High resolution 7T MRI is increasingly used to investigate hippocampal subfields in vivo, but most studies rely on manual segmentation which is labor intensive. We aimed to evaluate an automated technique to segment hippocampal subfields and the entorhinal cortex at 7T MRI. MATERIALS AND METHODS The cornu ammonis (CA)1, CA2, CA3, dentate gyrus, subiculum, and entorhinal...
متن کاملA non-linear gray-level appearance model improves active shape model segmentation
Active Shape Models (ASMs), a knowledge-based segmentation algorithm developed by Cootes and Taylor [1, 2], have become a standard and popular method for detecting structures in medical images. In ASMs – and various comparable approaches – the model of the object’s shape and of its gray-level variations is based the assumption of linear distributions. In this work, we explore a new way to model...

15 صفحه اولA Linear Algebraic Approach to Subfield Subcodes of GRS Codes
The problem of finding subfield subcodes of generalized Reed–Solomon (GRS) codes (i.e., alternant codes) is considered. A pure linear algebraic approach is taken in order to derive message constraints that generalize the well known conjugacy constraints for cyclic GRS codes and their Bose– Chaudhuri–Hocquenghem (BCH) subfield subcodes. It is shown that the presented technique can be used for fi...
