Fig. 8: Palm-center and crease tracking for three skin types to construct raw HSI Z-profiles (interferograms).

Five keypoints are detected by the AI-based tracking module palmTrack4Zprofiles.exe. Two cyan lines intersect to define the palm center, marked by a red target symbol (a “+” within a circle). Palm-crease detection, shown as green edges, is confined within the yellow triangular region.
