摘要

医学图像的保护方法有很多，最常用的有隐写、水印、加密等。由于水印技术的优点，它在图像安全领域取得了重要的地位。对Haar小波变换后的医学图像在不同子带上应用奇异值分解进行了对比分析。实验采用核磁共振成像和CT扫描医学图像。

DWT-SVD based reversible watermarking algorithm for embedding the secret data in medical images

There are different ways to protect medical images, most commonly used are steganography, watermarking, encryption etc. Due to the advantages of watermarking it has achieved a great importance in the field of image security. This paper gives a comparative analysis on applying SVD on different sub bands of a Haar wavelet transformed medical image. The experimentation is done using MRI and CT scan medical images.
