Conformal Warping on Brain Data
The surface of the human brain is highly folded, which makes visualization difficult. Without a simple visualization comparisons between cortical surfaces is incredibly complex. Most methods require characterization of each surface separately first, though methods exist for directly comparing the surfaces. Specifically, we use conformal mappings of triangulations of the cortical surface to warp two surfaces onto each other directly. We offer two methods for adaption from an existing warping algorithm due to Koehl and Hass, to account for surfaces with a boundary curve.
