Super-resolution techniques now provide an efficient strategy to improve the spatial resolution of individual diffusion maps. We extended this approach to a population of subjects and proposed a novel half-millimeter isotropic probabilistic atlas of the human brain connectivity, using the ARCHI database acquired in the frame of the European CONNECT connectome project. We demonstrate the efficacy of this approach combining a super-resolution technique based on high density streamline tractography and a robust segmentation technique of the white matter bundles.
