Description: 小波变换域图像水印算法是一种对图像多尺度的空间频率分解[13]，能更好地与人类视觉系统（HVS Human Visual System）相匹配。由于小波变换具有良好的时频局部性和多分辨率表示的特点，而且，当前最新的图像压缩标准——JPEG2000 和视频的MPEG-7 压缩标准都采用了小波变换，-The wavelet transform domain image watermarking algorithm is a multi-scale image of the spatial frequency decomposition [13], to better match the human visual system (HVS Human Visual System). Because the wavelet transform has good frequency characteristics of the locality and multiresolution representation, and, the latest image compression standard- JPEG2000 and video MPEG-7 compression standards have adopted the wavelet transform, Platform: |

Description: Wavelet compression algorithm. Start by computing a complete wavelet-transform using the cohen-daubechies-fevereau (2,2) biorthogonal wavelet (which incidentally seems to be the same as used for lossless JPEG2000, but they call it a (5,3)?). Platform: |

Description: Delphi:基于小波的JPEG2000图像压缩技术实例，由Delphi源代码实现，内含了小波动态连接库（vc实现），Delphi可借用这个类库。
首先必须注意的是，在小波变换的时候采用的是串行工作方式
这样一来，对于高速缓存的利用是十分低效率的，却可以节省不少的空间。
BIT.H BIT.C － 是有关比特位操作的代码
WAVELET.H WAVELET.C － 是小波操作的代码
函数输出： 函数返回转换象素的数目
1) Num：需要转换的连续象素的署名女
3)Y, Cb, Cr：同样是指针，分别指向三个结果的存放空间
-Delphi: JPEG2000 wavelet-based image compression techniques instance, achieved by the Delphi source code that contains the wavelet dynamic link library (vc achieve), Delphi can borrow this library.
First, it must be noted that, when the wavelet transform is used in a serial mode of operation
Thus, the use of cache efficiency is very low, it can save a lot of space.
BIT.H BIT.C- is a bit of code related operations
WAVELET.H WAVELET.C- is the code of wavelet operations
Output function: The function returns the number of pixels to convert
1) Num: women need to convert signature consecutive pixels
3) Y, Cb, Cr: same pointer, pointing to three storage space results Platform: |
