Raises:

Type Description
NotImplementedError

If the model is not found in the modelzoo.

Warns:

Type Description
UserWarning

If an fmpose3d model_name is used with a mismatched superanimal_name.

Note

(Model Explanation) SuperAnimal-Quadruped: superanimal_quadruped models aim to work across a large range of quadruped animals, from horses, dogs, sheep, rodents, to elephants. The camera perspective is orthogonal to the animal ("side view"), and most of the data includes the animals face (thus the front and side of the animal). You will note we have several variants that differ in speed vs. performance, so please do test them out on your data to see which is best suited for your application. Also note we have a "video adaptation" feature, which lets you adapt your data to the model in a self-supervised way. No labeling needed!

All model snapshots are automatically downloaded to modelzoo/checkpoints when used.

  • PLEASE SEE THE FULL DATASHEET: https://zenodo.org/records/10619173
  • MORE DETAILS ON THE MODELS (detector, pose estimators): https://huggingface.co/mwmathis/DeepLabCutModelZoo-SuperAnimal-Quadruped
  • We provide several models:
    • hrnet_w32 (Top-Down pose estimation model, PyTorch engine) An hrnet_w32 is a top-down model that is paired with a detector. That means it takes a cropped image from an object detector and predicts the keypoints. When selecting this variant, a detector_name must be set with one of the provided object detectors.
    • dlcrnet (TensorFlow engine) This is a bottom-up model that predicts all keypoints then groups them into individuals. This can be faster, but more error prone.
  • We provide one object detector (only for the PyTorch engine):

(Model Explanation) SuperAnimal-TopViewMouse: superanimal_topviewmouse aims to work across lab mice in different lab settings from a top-view perspective; this is very polar in many behavioral assays in freely moving mice.

All model snapshots are automatically downloaded to modelzoo/checkpoints when used.

(Model Explanation) SuperAnimal-Bird: superanimal_superbird model aims to work on various bird species. It was developed during the 2024 DLC AI Residency Program. More info can be found here

(Model Explanation) SuperAnimal-HumanBody: superanimal_humanbody models aim to work across human body pose estimation from various camera perspectives and environments. The models are designed to handle different human poses, activities, and lighting conditions commonly found in human motion analysis, sports analysis, and behavioral studies.

All model snapshots are automatically downloaded to modelzoo/checkpoints when used.

  • We provide:
    • rtmpose_x (Top-Down pose estimation model, PyTorch engine) An rtmpose_x is a top-down model that is paired with a detector. That means it takes a cropped image from an object detector and predicts the keypoints. When selecting this variant, a detector_name must be set with one of the provided object detectors. This model uses 17 body parts in the COCO body7 format.
  • The following object detectors can be used:

Tips: * max_individuals: make sure you correctly give the number of individuals. Our inference api will only give up to max_individuals number of predictions. * pseudo_threshold: the higher you set, the more aggressive you filter low confidence predictions during video adaptation. * bbox_threshold: the higher you set, the more aggressive you filter low confidence bounding boxes during video adaptation. Different from our paper, we now add video adaptation to the object detector as well. * detector_epochs and pose_epochs do not need to be to high as video adaptation does not require too much training. However, you can make them higher if you see a substaintial gain in the training logs. * scale_list: it's recommended to leave this as empty list []. Empirically [200, 300, 400] works well. We needed to do this as bottom-up models in TensorFlow are sensitive to the scales of the image. If you find your predictions not good without scale_list or it's too hard to find the right scale_list, you can try to use the PyTorch engine.

Examples:

Using the module import path:

import deeplabcut.modelzoo.video_inference.video_inference_superanimal as video_inference_superanimal
video_inference_superanimal(
    videos=["/mnt/md0/shaokai/DLCdev/3mice_video1_short.mp4"],

    model_name="hrnet_w32",
    detector_name="fasterrcnn_resnet50_fpn_v2",
    video_adapt=True,
    max_individuals=3,
    pseudo_threshold=0.1,
    bbox_threshold=0.9,
    detector_epochs=4,
    pose_epochs=4,
)

Using scale_list:

from deeplabcut.modelzoo.video_inference import video_inference_superanimal
videos = ["/path/to/my/video.mp4"]
superanimal_name = "superanimal_topviewmouse"
video_extensions = "mp4"
scale_list = [200, 300, 400]
video_inference_superanimal(
    videos,
    superanimal_name,
    model_name="hrnet_w32",
    detector_name="fasterrcnn_resnet50_fpn_v2",
    scale_list=scale_list,
    video_extensions=video_extensions,

        (Model Explanation) SuperAnimal-Quadruped:
        `superanimal_quadruped` models aim to work across a large range of quadruped
        animals, from horses, dogs, sheep, rodents, to elephants. The camera perspective
        is orthogonal to the animal ("side view"), and most of the data includes the
        animals face (thus the front and side of the animal). You will note we have
        several variants that differ in speed vs. performance, so please do test them
        out on your data to see which is best suited for your application. Also note we
        have a "video adaptation" feature, which lets you adapt your data to the model
        in a self-supervised way. No labeling needed!

        All model snapshots are automatically downloaded to modelzoo/checkpoints when
        used.

            https://huggingface.co/mwmathis/DeepLabCutModelZoo-SuperAnimal-Quadruped
        - We provide several models:
            - `hrnet_w32` (Top-Down pose estimation model, PyTorch engine)
                An `hrnet_w32` is a top-down model that is paired with a detector. That
                means it takes a cropped image from an object detector and predicts the
                keypoints. When selecting this variant, a `detector_name` must be set
                with one of the provided object detectors.
            - `dlcrnet` (TensorFlow engine)
                This is a bottom-up model that predicts all keypoints then groups them
                into individuals. This can be faster, but more error prone.
        - We provide one object detector (only for the PyTorch engine):
            - `fasterrcnn_resnet50_fpn_v2`
                This is a FasterRCNN model with a ResNet backbone, see
                https://pytorch.org/vision/stable/models/faster_rcnn.html

        (Model Explanation) SuperAnimal-TopViewMouse:
        `superanimal_topviewmouse` aims to work across lab mice in different lab settings
        from a top-view perspective; this is very polar in many behavioral assays in
        freely moving mice.

        (Model Explanation) SuperAnimal-Bird:
        `superanimal_superbird` model aims to work on various bird species. It was
        developed during the 2024 DLC AI Residency Program. More info can be
        [found here](https://deeplabcut.medium.com/deeplabcut-ai-residency-2024-recap-working-with-the-superanimal-bird-model-and-dlc-3-0-live-e55807ca2c7c)

        (Model Explanation) SuperAnimal-HumanBody:
        `superanimal_humanbody` models aim to work across human body pose estimation
        from various camera perspectives and environments. The models are designed to
        handle different human poses, activities, and lighting conditions commonly
        found in human motion analysis, sports analysis, and behavioral studies.

        used.

        - We provide:
            - `rtmpose_x` (Top-Down pose estimation model, PyTorch engine)
                An `rtmpose_x` is a top-down model that is paired with a detector. That
                means it takes a cropped image from an object detector and predicts the
                keypoints. When selecting this variant, a `detector_name` must be set
                with one of the provided object detectors. This model uses 17 body parts
                in the COCO body7 format.
        - The following object detectors can be used:
            - `fasterrcnn_mobilenet_v3_large_fpn` (default)
                This is a FasterRCNN model with a MobileNet backbone
            - `fasterrcnn_resnet50_fpn`
            - `fasterrcnn_resnet50_fpn_v2`
            For more info, see https://pytorch.org/vision/stable/models/faster_rcnn.html

        Tips:
        * max_individuals: make sure you correctly give the number of individuals. Our
            inference api will only give up to max_individuals number of predictions.
        * pseudo_threshold: the higher you set, the more aggressive you filter low
            confidence predictions during video adaptation.
        * bbox_threshold: the higher you set, the more aggressive you filter low
            confidence bounding boxes during video adaptation. Different from our paper,
            we now add video adaptation to the object detector as well.
        * detector_epochs and pose_epochs do not need to be to high as video adaptation
            does not require too much training. However, you can make them higher if you
            see a substaintial gain in the training logs.
        * scale_list: it's recommended to leave this as empty list []. Empirically
            [200, 300, 400] works well. We needed to do this as bottom-up models in
            TensorFlow are sensitive to the scales of the image. If you find your
            predictions not good without scale_list or it's too hard to find the right
            scale_list, you can try to use the PyTorch engine.
