Iris Fractal & Nevi Analysis: Comparative Study of Pigment Architecture and Pathology Markers — Argira Station (v2)

Key Points

The study aims to analyze the iris pigment architecture and nevi characteristics in human subjects using computational methods.
Utilized fractal geometry for quantitative analysis of iris pigment architecture.
Characterized nevi morphologically and mapped pigment distribution.
Employed Hough circle segmentation and adaptive thresholding for image analysis.
Calculated box-counting fractal dimension and HSV pigment quantification.
Subject A had a mean fractal dimension of 1.622 with 10 nevi detected and 75.1% pigment coverage.
Subject B showed a mean fractal dimension of 1.574, with 2 dominant nevi and 71.7% pigment coverage.
Two nevi in Subject A exceeded the vigilance threshold of D>1.7.

Abstract

This preprint presents a computational pipeline for quantitative analysis of iris pigment architecture in two human subjects using fractal geometry, nevi morphological characterization, and pigment distribution mapping. SUBJECT A: Brown iris. 10 nevi detected. Mean fractal dimension D=1.622 ± 0.121. Pigment coverage 75.1%. Two nevi above vigilance threshold D>1.7. SUBJECT B/OL: Green-hazel iris with sectorial heterochromia. 2 dominant nevi. Mean D=1.574 ± 0.132. Pigment coverage 71.7%. Infero-nasal pigment clustering pattern. METHODS: Hough circle segmentation, adaptive thresholding, box-counting fractal dimension, HSV pigment quantification, polar angular distribution analysis. NEXT VERSION (v3): Will add golden angle organization analysis (Auric Index A) connecting this work to the author's prior phyllotaxis research (Zenodo 18760369). Code and anonymized visual outputs only. No raw photographs included. Related: https://argiraacoustics.netlify.app/
