FlyWire: Online community for whole-brain connectomics

Le résumé fourni par la source

A ground truth dataset for 3D neuron reconstruction from electron microscopy (EM) images of the fly whole-brain, created for our project FlyWire: A human-AI collaboration to map the fly connectome.

Here intracellular structures are often oversegmented conservatively to prevent merge errors at the expense of introducing some split errors. glia.tar.gz Semi-automatically generated ground truth for glia detction. A set of subvolumes from the FlyWire segmentation was sampled from which human experts classified automatically generated segments into either neurons or glia, while existing merge errors were excluded from annotation.
