Geometry Research

Geometry extraction reports 20 bounded measurements including line density and orientation, entropy, parallel and perpendicular evidence, right-angle count, rectangularity, symmetry, spacing, regularity, convexity, compactness, aspect ratio, smoothness, irregularity, corners, and vanishing-point evidence.

Input is a normalized grayscale region of at least 8×8 pixels. Boundary-sensitive values remain missing when a boundary is unavailable; they are not replaced with invented evidence.
