A new directional colormap for DTI fiber tractography and its application to bundle recognition

We propose a new tractography colormap based on the HSL model to complement the classical RGB colormap used in the field. Our colormap is based on a new feature, called "streamlines normal", an oriented vector that is computed from the tractography. The streamlines normal in combination with the HSL colormap improves tractography data visualization and can be an asset for better and faster bundle segmentation both manually and automatically.
