Peter Skovorodnikov and I are excited to present FERAL: a new video-understanding toolkit that maps raw video directly to behavior, no pose estimation required.
It works across species, from lab to field, and even in collective systems. (🧵1/n)

FERAL: A Video-Understanding System for Direct Video-to-Behavior Mapping
Animal behavior unfolds continuously in time, yet quantitative analyses often require segmenting it into discrete, interpretable states. Although manual annotation can achieve this, it remains slow, s...
