- dwt算法数字水印matlab程序算法的实现-dwt algorithm of digital watermarking algorithm matlab procedures
DWT_shuiyin
- 提出了一个新的基于量化抖动和模式分组编码的盲数字图像水印算法,该算法首先在DWT(离散小波变换)的第 二层中频子带中随机选取相应位置的绝对值最大的系数作为水印的嵌入区间,对小波系数进行量化并根据分组编码原 理生成预嵌入模式,然后将一个二值水印图像嵌入到模式当中。-Proposed a new model based on quantitative jitter and packet-coded blind digital image watermarking algorithm, the
DWT-matlab
- 小波变化实现图像的压缩，图像复原，图像的编码等，用matlab实现的-Wavelet transform for image compression, image restoration, image coding, matlab implementation

- this is coding of dwt in matlab
Undecimated-DWT
- 对Lena图先进行jpeg压缩，再对压缩后的图像分别进行小波软阈值去噪和非抽样硬阈值去噪，比较两种去噪方案，非抽样硬阈值有更好的效果。这是根据一篇外文文献来进行编程的，最后有图像对比结果。-According to the paper of OPTIMAL WAVELET THRESHOLDING FOR VARIOUS CODING SCHEMES ,I firstly compresse the Lena picture using the jpeg method ,then respect
DCT-DWT
- 对图像实现DCT，DWT编码压缩及重建，是一个很好的学习入门东西。附加文档说明-Images to achieve DCT, DWT compression coding and reconstruction, is a good learning portal thing. Additional documentation
