DataJoint Element - DeepLabCut

This repository features a DataJoint schema for pose estimation via DeepLabCut. The pipeline presented here is not a complete pipeline by itself, but rather a modular design of tables and dependencies specific to the behavior tracking workflow. This modular pipeline element can be flexibly attached downstream to any particular design of experiment session, thus assembling a fully functional behavior pipeline (see the example workflow-deeplabcut).

This Element currently supports single-animal, single-camera 2D models, and does not yet support multi-animal or multi-camera models. This Element does not offer any features for labeling training data. Users should to use native DeepLabCut tools for intitializing a project and labeling training data.

• See the Element DeepLabCut documentation for the background information and development timeline.

Element architecture

As the diagram depicts, the DeepLabCut element starts immediately downstream from a Session table, which is modeled in our workflow pipeline. The following tables are further downstream across two schemas:

• train schema: Tables related to model training.
  • VideoSet: The set of files corresponding to a training dataset.
  • TrainingParamSet: A collection of model training parameters, represented by an index.
  • TrainingTask: A set of tasks specifying model training methods.
  • ModelTraining: A record of training iterations launched by TrainingTask.
• model schema: Tables related to DeepLabCut models and pose estimation.
  • VideoRecording: Video(s) from one recording session, for pose estimation.
  • BodyPart: Unique body parts (a.k.a. joints) and descriptions thereof.
  • Model: A central table for storing unique models.
  • ModelEvaluation: Evaluation results for each model.
  • PoseEstimationTask: A series of pose estimation tasks to be completed. Pairings of video recordings with models to be use for pose estimation.
  • PoseEstimation: Results of pose estimation using a given model.

Installation

• Install element-deeplabcut

  pip install element-deeplabcut
  

• Upgrade element-deeplabcut previously installed with pip

  pip install --upgrade element-deeplabcut
  

• Install element-interface

  • element-interface is a dependency of element-deeplabcut, however it is not contained within requirements.txt.

  pip install "element-interface @ git+https://github.com/datajoint/element-interface"
  

Usage

Element activation

To activate the element-deeplabcut, one needs to provide:

1. Schema names
   • optionally, a schema name for the train module.
   • a schema name for the model module.
2. Upstream tables
   • Session: A set of keys identifying a recording session (see Element-Session).
   • Device: A reference table linked VideoRecording to specify camera information.
3. Utility functions
   • get_dlc_root_data_dir() to provide a root directory for a given machine,
   • optionally, get_dlc_processed_data_dir() to provide an output directory.

For more detail, check the docstring of the element-deeplabcut:

    help(train.activate)
    help(model.activate)
