Automating segmentation of individual neurons in electron microscopic (EM) images is a crucial step in the acquisition and analysis of connectomes. It is commonly thought that approaches which use contextual information from distant parts of the image to make local decisions, should be computationally infeasible. Combined with the topological complexity of three-dimensional (3D) space, this belief has been deterring the development of algorithms that work genuinely in 3D. . Lecture . 17: More .
