Paper: DeepLabCut

Summary

  1. present an efficient method for markerless pose estimation based on transfer learning with deep neural networks;
  2. by labeling only a few hundred frames, one can train tailored, robust feature detectors that are capable of localizing a variety of experimentally relevant body part;

Proble Statement

  • inhomogeneous illumination; transparent side walls that appear dark; shadows around the mouse from over head lighting; distortions due to a wide-angle lens; the frequent crossing of the mouse over the odor trail; the common occurrence of rewards directly in front of its snout;

previous work:

  • physical markers;
  • fit skeleton or active contour models13-17;
  • training regressors based on various computationally derived features to track particular body parts in a supervised way;

Methods

  • Problem Formulation:

  • system overview:
