How the score and four dimensions are calculated

AttractiveNet supplies the overall PSL score. Your photo is area-resampled to 350 × 350 RGB pixels and scored locally in your browser. MediaPipe measures the original photo geometry for Harmony, Dimorphism, Angularity and Symmetry.

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.

The green bar highlights the community golden aesthetic range. The vertical marker shows your photo measurement, and the thin spread indicates minor lighting or pose variations.

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.

The points behind the picture.

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.

Eye angles share the same photo.

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.
