Description: This paper describes the evolution of new wavelet and scaling numbers for optimized transforms that consistently outperform the 9/7 discrete wavelet transform (DWT) for fingerprint compression and reconstruction. The FBI fingerprint compression standard [2] is based upon the biorthogonal 9/7 wavelet filter pair developed in 1992 by Cohen, Daubechies, and Feauveau [3].

Description: 信息隐藏与水印技术系列实验之三：DWT变换域可见图像水印算法（开发工具：vc2005）：实现在一个256色灰度载体图像变换域数据中嵌入一个256色灰度文本图像水印。其主要功能如下：
（1）可以载入不同的载体图像和水印图像，但载体图像和水印图像在本软件中被限制为256色灰度图像，若要用其它图像甚至彩色图像，请修改源码。
（2）水印在载体图像中的嵌入位置及嵌入强度可以设置。
（3）可以计算原始图像和含水印图像的峰值信噪比（PSNR），以对含水印图像进行客观质量评价。
（4）源码结构清晰，在其基础上可快速开发出自己的水印软件。-err

Description: 信息隐藏与水印技术系列实验之四：DWT变换域不可见图像水印算法（开发工具：vc2005）：
实现在一个256色灰度载体图像的DWT变换域低频LL系数中多次重复嵌入一个256色灰度文本图像水印。其主要功能如下：
（1）可以载入不同的载体图像和水印图像，但载体图像和水印图像在本软件中被限制为256色灰度图像，若要用其它图像甚至彩色图像，请修改源码。
（2）可以对含水印图像中的水印信息进行提取，提取时需要原始图像。
（3）剪切攻击可使含水印图像中的水印信息部分丢失。
（4）可以计算峰值信噪比（PSNR）和互相关系数（NC），以对含水印图像及提取水印进行客观质量评价。
（5）源码结构清晰，在其基础上可快速开发出自己的水印软件。-err

Description: 本文提出了一种基于提升算法的高效JPEG2000二维离散小波变换(2D—DWT)~ 结构，将边界延拓内嵌于离散小波变换过程中，减少了所需的内存空间和功耗。采用W 扫描输入方式和行列并行处理结构，加快了变换速度，大大提高了小波变换的效率。整个二维离散小波变换结构已经通过FPGA硬件仿真验证。-This paper presents a highly efficient algorithm based on lifting JPEG2000 two-dimensional discrete wavelet transform (2D-DWT) ~ structure, the boundary extension will be embedded in the process of discrete wavelet transform to reduce the required memory space and power consumption. W scanning input methods used and the ranks of parallel processing structure, and accelerated the pace of change has greatly enhanced the efficiency of wavelet transform. The whole structure of two-dimensional discrete wavelet transform has been adopted FPGA hardware simulation.
