AI mouse facial analysis system for high-precision, stable whisker and micro-expression phenotyping — quantifying squinting, ear posture, and whisker dynamics as objective metrics.
From chronic pain models to postoperative analgesia and pain–emotion comorbidity research, quantifying mouse facial and whisker micro-behaviors is central to objective pain phenotyping.
See the micro-expressions to understand pain mechanisms — quantifying facial dynamics objectively is the first step in pain assessment.
Most methods rely on paw licking and head shaking while struggling to capture whisker tremor, squinting, and ear posture changes — low-amplitude, fast micro-expressions that manual scoring and low-frame-rate video cannot quantify objectively.
AI facial detection, high-speed tracking, and multi-dimensional parameters for pain and emotion phenotyping.
Advanced AI algorithms capture high-frequency, low-amplitude whisker micro-movements and subtle facial dynamics.
Integrated pipeline: facial video capture → AI keypoint tracking → analysis → visualization.
High-speed imaging with adjustable frame rates up to 1000 fps for rapid facial and whisker micro-movements.
Stable tracking of 5+ core points — nose tip, whisker base, and three whisker tip points — with continuous x,y coordinates.
Trajectory, velocity, acceleration, swing angle, power, curvature, and more for in-depth facial dynamics.
Extensible algorithms support additional keypoints such as pupils and snout for diverse research paradigms.
Facial capture hardware, acquisition software, and analysis software — end-to-end from video capture to chart export.
