数字水印源码
- 是关于数字水印的空域算法原代码,用的是delphi7.0。是把二值水印嵌入到原图像的低三位的嵌入算法-This is a watermark soucecode based on Spacial Domain Algorithm implemented by using Delphi7.0. The main idea is to embed the binary watermark into the primary image.
JPEG2000_9_7_002.pdf
- 基于实数的二进制表示法,把CDF(Cohen,Daubechies and Feauveau)9/7双正交小波基的提升系数化为二进制,采用简单的移位一加操作代替结构复杂的浮点乘法器,从而实现了JPEG2000中9/7离散小波变换的定点计算.相对于浮点计算法,移位一加操作最大的优点是计算简单,特别易于超大规模集成电路实现,因而使硬件实时处理图像信号成为可能.实验仿真结果表明:在低压缩比的情况下,用移位一加操作重构的图像,其峰值信噪比(PSNR)只比浮点法低0.10 dB,当压缩比增大时,其PSNR
wavelet
- 小波变换的一级分解过程,原始信号分别进行低通、高通滤波,再分别进行二元下抽样,就得到低频、高频(也称为平均、细节)两部分系数;而多级分解则是对上一级分解得到的低频系数再进行小波分解,是一个递归过程-Wavelet decomposition level, the original signals were low-pass, high pass filter, and then under the random binary respectively, to be low frequency,
