An original image is compressed with fuzzy transforms and is divided in images of sizes 2×2 on which we apply a known fragile watermarking process. A preprocessing phase is considered to determine the better compression rate for the coding process. We test this scheme in tamper detection analysis on a sample of images. The results are good in terms of accuracy for tamper detection with compressed images and in terms of dimension of the image dataset used for storage of the original images.

Abstract
An original image is compressed with fuzzy transforms and is divided in images of sizes 2×2 on which we apply a known fragile watermarking process. A preprocessing phase is considered to determine the better compression rate for the coding process. We test this scheme in tamper detection analysis on a sample of images. The results are good in terms of accuracy for tamper detection with compressed images and in terms of dimension of the image dataset used for storage of the original images.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
