Micro-Expression–Based Facial Analysis for Automated Pain Recognition in Dairy Cattle

2025-06-30

Abstract excerpt

Timely, objective pain recognition in dairy cattle is essential for welfare assurance, productivity, and ethical husbandry, yet remains elusive because evolutionary pressure renders bovine distress signals brief and inconspicuous. Without verbal self‑report, cows suppress overt cues, so automated vision is indispensable for on‑farm triage. Earlier systems tracked whole‑body posture or static grimace scales; frame‑...
