Bayesian approaches in multi-modal MRI segmentation, reading group presented by
Igor Varga, K333 (


Statistical shape models provide a framework which is capable of combining
strong prior information (e.g. a 3D anatomical atlas) with patient data, such
multi-modal MRI. In this reading group, the main focus will be on application
this approach to sub-cortical MRI segmentation, represented mainly by Visser
et al. [1]. The paper presents a method which allows learning from unsupervised
data and combining multiple MRI modalities at the same time.

Preceding works by Patenaude et al. [2],[3],
are recommended for a well explained overview and introduction to the topic
through a simple single-modality supervised bayesian version of the method.
