Anatomical Segmentation

  • Ensures consistent region definition

  • Prevents variability in measurement location

Motion Compensation

  • Maintains spatial consistency over time

  • Corrects for eye and head movement

Artifact Exclusion

  • Removes blink-related distortions

  • Ensures only valid frames are analyzed

This pipeline ensures that all measurements are derived from anatomically consistent and physiologically valid data.

Synchronized Thermal–Visible Acquisition

Thermal and visible cameras are hardware-synchronized to capture spatially aligned data at the same time point.
Dual-Modal Acquisition

Captures temperature and anatomy simultaneously
