Author's colleague here. Rosti wrote this after we kept running into the same problem across customer sites.

The core formula is Dan Paquette's proportional normalization (aspect ratio raised to a scale factor), but the density compensation and visual center-of-mass calculation are the interesting additions.

The visual center algorithm weights each pixel by sqrt(colorDistance) * (alpha / 255) to find where the "ink" actually lives vs. the geometric center. It's a subtle effect but makes a noticeable difference with asymmetric logos.
