Spectral Analysis of Topological Surfaces: Application to A Cortical Surface and Functional Maps

The study of brain functions requires accurate and precise matching of cortical surface data in order to compare brain activities with a population. In this context, several tasks such as surface inflation for measurements and cortical visualizations, surface matching are fundamental. Present methodologies are typically expensive and rely on anatomical features. In this study, we review a newly proposed method incorporating cortical smoothing, point matching and transfer of functional maps, all together with only some minutes of computation. This Brain Transfer is based on spectral analysis.
