SVD_DWTimage.rar
提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块,对每一块进行奇异值分解后,选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。

是基于LeventCodes平台作的。BivaShrink方法、模型1、模型2、模型3(TrivaShrink方法)、BayesShrink方法、
LAWMLShrink方法的DWT实现和DT_CWT实现。

this code first reads an image and decomposed it in discrete wavelet transformation.hl1 and hl2 are extracted to embed watermark. watermark is added to hl1 and lh1 and inverse dwt is applied.

此示意程序用DWT实现二维小波变换
1.调原始图像矩阵load wbarb
2.进行二维小波分解l=wfilters( db10 , l )
3.分解结果显示figure(1)
