摘要

原始图像用模糊变换压缩，并被分割成大小为2×2的图像，在这些图像上我们应用已知的脆弱水印过程。考虑预处理阶段以确定编码过程的较好压缩率。我们在一个图像样本上对该方案进行了篡改检测分析。就压缩图像的篡改检测的准确性和用于存储原始图像的图像数据集的维度而言，结果很好。

Fuzzy Transforms and Fragile Watermarking Tamper Detection on Coded Images

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.
