Decerner is fully transparent: there is no black box. Below is exactly how a photo becomes a 0–100 score.

The pipeline

01

Upload

A clear, front-facing photo.

02

Detect

Facial landmarks are located automatically.

03

Measure

14 geometric proportions are computed.

04

Score

A 0–100 score, breakdown and radar profile.

How scoring works

Each coefficient compares a measured value to a classical ideal and scores it with a smooth Gaussian falloff. The final score is the average of all 15.

Symmetry & Balance

Landmarks are mirrored across the vertical midline to measure how evenly the left and right halves align.

Ratios & Proportions

The golden ratio, facial thirds, the five-eye rule and other neoclassical canons are measured against their ideal values.

Transparent Scoring

No black box. Every coefficient shows the exact formula and the measured value.

What this is — and isn’t

Beauty is subjective and shaped by culture. Decerner does not judge your worth or decide who is attractive — it measures how closely your facial geometry matches proportions that have been studied for centuries. Read your score as a fun, geometric perspective, not an objective verdict.
