  • Persians catalog portrait, AI-generated, eyes in view

Catalog portraits for Persians are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.

Iris color

n = 62 assessable · 16 not assessable

Predominant color of the iris. Heterochromia is captured as its own value; mixed colors (e.g. hazel, blue-green) get distinct buckets.

ValueSharen
dark brownIris appears nearly black under typical lighting; high melanin content. Common in East Asian, South Asian, Sub-Saharan African, and indigenous populations.92%57
brownMedium to dark brown iris; visible iris detail.3%2
hazelMixed brown and green/gold; central iris differs in color from peripheral iris (central heterochromia).2%1
greenTrue green; uncommon globally, concentrated in Northern and Eastern European populations.2%1
blueTrue blue; highest frequency in Northern European populations, decreases southward.2%1

Vocabulary: Iris color (iris_color_qualitative)

Epicanthic fold

n = 73 assessable · 5 not assessable

Presence and morphology of the epicanthic fold — the skin fold of the upper eyelid that may cover the medial canthus. Significant ethnic variation; high prevalence in East Asian, Central Asian, and indigenous American populations.

ValueSharen
absentNo epicanthic fold; medial canthus clearly visible.100%73

Vocabulary: Epicanthic fold (duke_elder_epicanthus_classification)

Eye shape

n = 73 assessable · 5 not assessable

Overall shape of the visible eye, considering the silhouette of the upper and lower lid margins together. Independent dimension from eyelid_crease_type and epicanthic_fold, which capture finer morphological variation.

ValueSharen
almondSlightly elongated horizontal axis; mild taper at lateral and medial canthi. Considered the aesthetic reference shape.70%51
deep-setEye sits deep within the orbital socket; pronounced shadow above the upper lid. Brow ridge typically prominent.27%20
hoodedUpper lid skin descends over the lid crease, partially or fully covering the upper lid platform. Often associated with periorbital aging but can be constitutional.1%1
roundVertical and horizontal axes approximately equal; minimal canthal taper. Visible sclera above and below the iris.1%1

Vocabulary: Eye shape (eye_shape_qualitative)

Where these numbers come from

78 publicly documented portraits of notable Persians people were assessed by a vision model against the catalog vocabulary, one row per portrait. Values are what the photographs show, read by a model, not population measurements. Each table counts only portraits where the value could be assessed; covered, obscured and unclear portraits are reported separately.

Notable-people corpora skew older, so hair color over-represents gray and white, and image quality varies. Treat shares as a description of this sample. Mean model confidence for this family: 0.65. 44% of portraits are high quality.

The same rows are published as image_observations in the catalog dataset; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
