摘要:数字水印是解决数字产品版权的重要手段,为保护数字水印的安全性,需采用加密技术。本文应用labVIEW软件搭建了一个数字图像处理系统,实现了数字图像水印的加密操作。该系统采用Toral置换技术来改变数字图像像素点的坐标值,使图像变混乱。系统还可计算出规格图像的变换周期,图像在经过周期次数转换时会还原为原始图像。通过对两幅图片进行实际操作,证实了系统工作正常。

The Experiments of Digital Image Transformation Based on LabVIEW
Abstract:Digital watermarking is an important mean to solve the problem of copyright of digital products.With the purpose of protecting digital watermarking security, we need use the encryption technology. This paper introduces a digital image processing system based on labVIEW software, which achieves digital image watermark encryption. The system uses Toral transformation technology to change the coordinates of digital image pixel and make the image confusing.The system can also calculate the transformation cycle of the image , the image will revert to the original image after transforming by the period times. By the actual operation of two pictures, the system is convinced working properly.
