How the score and four dimensions are calculated

AttractiveNet supplies the overall PSL score from a 350 × 350 RGB input prepared by your browser. Our Cloudflare service runs AttractiveNet and MediaPipe; the browser uses the returned data to calculate and display Harmony, Dimorphism, Angularity and Miscellaneous.

PSL score: S = clip(1 + 1.75 × (AttractiveNet − 1), 1, 8)
Geometry adjustment: δᵢ = 9 × rᵢ
Anchored dimension: Dᵢ = clip(S + δᵢ − 0.5 × Σ(wⱼ × δⱼ), 1, 8)
Dimension weights: w = [0.35, 0.20, 0.25, 0.20]

The 16 measurements enter fixed feature curves. Their weighted contributions form each group's relative value r. The four dimensions are anchored to the overall score, with room for strengths and weaker areas; their average is not forced to equal PSL. Measurement explanations, highlights and styling priorities use these same weighted curves.

Green segments mark ranges with a positive contribution in the current model's frozen feature curve, not a population-wide ideal range. The marker is your photo measurement; its spread models point-placement sensitivity, not a confidence interval for lighting or pose.

Each displayed contribution is 9 × feature-curve value × consistency weight. Contributions sum within their group before the shared weighted anchoring correction and 1–8 clipping. Highlights and priorities use these same contributions. Reference segments are limited to the model's recorded feature range.

Landmarks and measurement definitions

Landmark numbers follow the MediaPipe 478-point face topology. The horizontal axis follows iris centres 468 and 473. W is the projected width between cheek points 234 and 454; H is brow points 105, 52, 334 and 282 averaged to upper lip point 0. V is iris-midpoint to mouth-midpoint height; D is iris-centre distance. All coordinates are photo-space measurements.

Example: width 160 ÷ height 80 = FWHR 2.00. Scaling both lengths by the same amount leaves the ratio unchanged.

Canthal tilt formulas

Inner and outer eye corners use 133/33 and 362/263. Eye analysis reports each angle relative to the iris reference line, alongside its point-placement range. The full-face angularity group uses the 2D angle formula shown above.
