Description: 此程序用提升法实现第二代小波变换
我用的是非整数阶小波变换
采用时域实现,步骤先列后行
正变换：分裂，预测，更新；
反变换：更新，预测，合并
只做一层（可以多层，而且每层的预测和更新方程不同）-procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different) Platform: |

须得以确认。提出一种结合Zernike 矩的半脆弱水印算法,利用图像小波变换低频子带的Zernike 矩幅值的半脆弱特性区
分恶意攻击和偶然攻击,提高了水印的安全性,并能准确地定位出篡改区域。-With the rapid development of the image techniques , If the image contains important data , such as politics ,
military , commerce and evidence , the authenticity and integrality of the image must be validated. In this paper , a semi2f ragil2
eim watermarking algorithm using Zernike moment s is proposed , it can distinguish malicious modification f rom incidental
modification according to semi2f ragile characteristics of zernike moment s of the low f requency subband in the integer wavelet
