We present a fragile colour image watermarking based on the greatest solution of a bilinear fuzzy relation equation. The original image is coded with fuzzy transforms and divided in sub-images of sizes 2×2 called blocks. The watermark is applied on these blocks. A pre-processing phase is used to determine the best compression rate for the coding process. We test this scheme in tamper detection analysis on a sample of colour images of different sizes. Comparisons with various block-based fragile watermarking methods are presented as well.

Abstract
We present a fragile colour image watermarking based on the greatest solution of a bilinear fuzzy relation equation. The original image is coded with fuzzy transforms and divided in sub-images of sizes 2×2 called blocks. The watermark is applied on these blocks. A pre-processing phase is used to determine the best compression rate for the coding process. We test this scheme in tamper detection analysis on a sample of colour images of different sizes. Comparisons with various block-based fragile watermarking methods are presented as well.| File | Dimensione | Formato | |
