MICrONS: Machine Intelligence from Cortical Networks

A ground truth dataset for 3D neuron segmentation from electron microscopy (EM) images of mouse visual cortex, created for IARPA's Machine Intelligence from Cortical Networks (MICrONS) program.

Every volume has an attribute resolution that specifies the voxel size in nm. image segmentation mitochondria (optional) synapse (optional): annotation for postsynaptic densities (PSDs) fold (optional): annotation for folds (a kind of image defect) in images mask: valid/invalid voxels are represented as 1s/0s respectively. annotations: are incomplete, meaning that each volume may or may not contain proper annotations. object_ids (optional): small unidentified objects or intracellular organelles that are oversegmented, which may require special handling. myelin_ids (optional) blood_vessel_ids (optional) soma_ids (optional) nucleus_ids (optional)
