Iridology Analysis Toolkit is a research and educational tool for capturing, analyzing, and documenting iris patterns using classical mapping techniques and AI-assisted zone detection.

Core Algorithm Components:

Iris Detection

Uses grayscale image processing to locate the iris boundary
Employs a circle-scoring algorithm that searches for the strongest edge gradient

Two-pass detection: coarse search followed by fine refinement
Returns center coordinates, radius, and confidence score

Pupil Detection

Searches within the inner portion of the detected iris

Uses adaptive thresholding based on the darkest 30% of pixels

Fits an ellipse to the dark region using covariance matrix eigenvalue decomposition

Extracts boundary points by ray-casting from center outward
Returns center, major/minor axes, orientation angle, and boundary points

Pupil Boundary Analysis

Analyzes 72 boundary points (every 5 degrees) around the pupil edge
Calculates deviation from the average radius at each clock position
Groups deviations by clock hour (12 zones)
Identifies flattenings (inward deviations) and protrusions (outward deviations)

ANW (Autonomic Nerve Wreath) Detection

Searches for gradient changes between pupil edge and mid-iris
Identifies the collarette boundary
Calculates ANW ratio relative to iris diameter
Algorithm updates include:
SHIFTS (Drawing Out)
Which zone the collarette bulges toward

CONSTRICTIONS (Drawing In) Frontal zone constricted S: Middle-temporal shift. ← Drawing OUT (protrusion), S: Frontal and basal zones are constricted. ← Drawing IN (narrowing)
Basal zone constricted
Combined “Frontal and basal” pattern
Both in Same Eye
Correctly reports both when present
ANW Form Type – Regular, Drawn In, Drawn Out
ANW Asymmetry – Per-sector variance detection
Zone Constrictions – “Frontal zone constricted” style reporting
Pattern Correlation – Compare pupil and ANW findings by sector

Zone-Specific Organ Associations

Each of the 8 pupil zones has specific organ associations for:

Flattenings – Indicating hypofunction/weakness

Protrusions – Indicating hyperfunction/irritation
