In this paper, we introduce a novel algorithm for segmentation of imperfect\nboundary probability maps (BPM) in connectomics. Our algorithm can be a\nconsidered as an extension of spectral clustering. Instead of clustering the\ndiffusion maps with traditional clustering algorithms, we learn the manifold\nand compute an estimate of the minimum normalized cut. We proceed by divide and\nconquer. We also introduce a novel criterion for determining if further splits\nare necessary in a component based on it's topological properties. Our\nalgorithm complements the currently popular agglomeration approaches in\nconnectomics, which overlook the geometrical aspects of this segmentation\nproblem.\n
