Image Segmentation Adapted for Clinical Settings by Combining Pattern Classification and Level Sets
An efficient clinical image segmentation framework is proposed by combining a pattern classifier, hierarchical and coupled level sets. The framework has two stages: training and segmentation. During training, ...

Scale-Invariant Registratiou of Monocular Endoscopic Images to CT-Scans for Sinus Surgery
We present a scale-invariant registration method for 3D structures reconstructed from a monocular endoscopic camera to pre-operative CT-scans. The presented approach is based on a previously presented method [...

Learning Coupled Prior Shape and Appearance Models for Segmentation
We present a novel framework for learning a joint shape and appearance model from a large set of un-labelled training examples in arbitrary positions and orientations. The shape and intensity spaces are unifie...

Fast Non-linear Elastic Registration in 2D Medical Image
Non-linear image registration can match two images’ local areas exactly. Linear elastic model that obeys the Navier-stokes equilibrium equations is especially fit for image registration with small deformation....

Measurement of 3D motion of myocardial material points from explicit B-surface reconstruction of tagged MRI data
MRI is unique in its ability to non-invasively and selectively alter tissue magnetization, and create tag planes intersecting image slices. The resulting grid of signal voids allows for tracking deformations o...
