Image Registration Overlay

Align two local images with auditable control points or bounded translation correlation.

Visual comparison only: browser decoding, embedded color profiles, resampling, and interpolation can alter pixels. This is not scientific, survey, metrology, medical, or forensic registration and makes no accuracy claim.

Comparison

Nudge B:

Out-of-bounds pixels are transparent. RGB-channel RMSE and the histogram use only pixels where both images have nonzero alpha. PNG export keeps the A-sized canvas; no automatic crop is applied.
