MRI Head Pose & Expression Analysis System
Head Pose · Expression Recognition
AI-based facial landmark detection computes head rotation angles (pitch, roll, yaw) and head displacement, with real-time facial expression recognition and 3D digital-twin visualization of head motion. Provides objective data for head-motion monitoring, emotion assessment, and scan quality control in MRI environments — with value in neuroimaging and clinical psychology research.

3D digital twin visualization
Maps head motion to a 3D digital model — intuitive angle and displacement trajectories for real-time QC decisions.
Head Pose
Facial-landmark-based head motion parameters — objective quantification of head movement during scans.
Pitch angle
Head nod up/down rotation — anterior-posterior nodding motion.
Roll angle
Head tilt left/right — lateral roll motion capture.
Yaw angle
Head turn left/right — lateral rotation during scanning.
Head displacement
3D translational displacement — macro head motion beyond angular thresholds.
Head-motion threshold alerts
Configurable angle and displacement thresholds with real-time alerts for scan QC.
Temporal motion log
Full-session head-motion time series — alignable with fMRI temporal data.
Expression Recognition
Real-time facial expression recognition — behavioral readouts for emotion assessment and task-evoked response analysis.
01
Basic expression recognition
Detects happiness, sadness, surprise, fear, anger, disgust, and intensity levels.
02
Micro-expression & dynamics
Captures expression onset, peak, and offset — parsing brief emotional fluctuations.
03
Task-evoked responses
Links fMRI task blocks to expression changes — supporting emotion-processing mechanism research.
04
Individual baseline profiling
Subject expression baseline profiles improve cross-session emotion assessment comparability.
3D Visualization
