Case Study 2: 95 images were used to train DeepLabCut to predict 22 labels on the chestnut horse (video 1). Automatic labeling was then performed on the full video of chestnut and a previously unseen brown horse (video 2).
Video 3 is taking DeepLabCut, first trained on the chestnut horse (video 1), then adding only 11 labeled frames of Justify on a race track, re-training briefly, and applying the automatic labels to the full video. Note the differences in background, change of viewpoint, as well as the different relative sizes of the horse in video 3 vs video 1.

Case Study 3: Left: Mouse locomotion. Data, labeling, DeepLabCut training & video generation by Rick Warren in Dr. Nate Sawtell's lab at Columbia University. Shown here are the 3D movements from a head-fixed mouse running on a treadmill as collected by one camera (plus a mirror). One network was trained to detect the body parts in both views simultaneously. He used 825 frames of data for training (fewer labels would give similar performance). Here is more information and open source building designs for Rick’s KineMouse Wheel.

Right: a beta-fish tracked with DeepLabCut by Claire Everett, from the lab of Andres Bendesky at Columbia University.
Case Study 4: James Bonaiuto, PhD (a postdoctoral fellow in the group of Dr. Pier F. Ferrari at the Institut des Sciences Cognitives, CNRS) trained three networks - one trained on each view with ~120 training frames per view. The 3D trajectories were extracted by using the camera calibration functionality in openCV to compute a projection matrix for each camera and then using these to reconstruct the 3D coordinates from the labeled 2D points in each view.
Case Study 5: Open field with objects and a patch cable. Korleki Akiti a PhD student in the laboratory of Prof. Nao Uchida, at Harvard University labeled data for mice in an open field setting, and then we tested DeepLabCut's ability to track the 4 parts on a mouse (snout, ears, tail base) in different light conditions. A test image under a normal lighting condition is on the left, and two challenging examples are shown in the middle and right panels:
Case Study 7:Thomas Vaissière, PhD from the Scripps Institute in FL is using DeepLabCut for pupil tracking. he compared low-resolution and a high resolution camera and obtained a similar performance, even with training for only 40 images (also see pupil tracking from the International Brain lab, here).
