How FaceIQ Compares Two Faces Scientifically
Rather than subjective human voting or arbitrary machine scoring, FaceIQ's side-by-side comparison engine extracts exact craniofacial coordinates using MediaPipe's sub-millimeter 478-point mesh. Both faces are normalized for rotation, roll, and distance, allowing precise mathematical comparison of key sexual dimorphism markers: canthal inclinations, bizygomatic width-to-height ratio (FWHR), gonial mandibular angles, and midline bilateral symmetry.

👥 Sibling & Friend Battles
Compare facial proportions with friends or siblings to see which features follow maternal vs paternal genetic patterns.
⭐ Celebrity Benchmark
Test your facial harmony against top-tier supermodels and actors to see how your orbital and jawline metrics compare.
How Objective dual portrait comparison works
Performing a rigorous face comparison requires calculating sub-millimeter trigonometric vectors rather than subjective opinions. When contrasting two facial portraits, our system maps 478 MediaPipe neural landmarks to assess differences in palpebral canthal tilt, facial width-to-height proportions (FWHR), and bilateral symmetry.
Whether you are assessing subtle aesthetic improvements across fitness journeys, analyzing genetic resemblance between siblings, or tracking orthodontic shifts over time, side-by-side anthropometric evaluation isolates real structural contours from lighting and camera focal length variances.
Unlike traditional cloud services, every computational landmark calculation is performed exclusively inside your browser sandbox. Neither portrait is uploaded or retained, guaranteeing complete biometric confidentiality while you explore side-by-side morphological harmony.
