SLEAP is an open source deep-learning based framework for multi-animal pose tracking. It can be used to track any type or number of animals and includes an advanced labeling/training GUI for active learning and proofreading. Documentation
SLEAP has developed NDXPoseAdaptor , an adaptor class within SLEAP for importing and exporting NWB files. Users can either use the SLEAP GUI to import/export NWB files or use the high-level API Labels.export_nwb to programatically export to the NWB format. This adaptor uses the NWB extension ndx-pose, which aims to provide a standardized format for storing pose estimation data in NWB.
