摘要

提出了三种基于子波变换的图像处理技术先对图像数据进行二维离散于波变换，根据子波变换后高。低频分量的特点，数据隐含技术将加密数据隐藏在于波变换图像的高频部分最低两位；加扰采用改变子波变换图像的低频部分，以此干扰复原图像质量；防伪是在原图像中改动某些象素值，使在子波变换图像的高频部分得到某种显而易见的标志，以此分辨图像的真伪．这三种技术处理都是基于子波变换后的图像，几乎没有附加传输信息量，所以基于子波变换的图像压缩技术对上述处理后的图像依然适用．

Abstract

This paper proposes three kinds of image process technology based on wavelet transform. First

image data are processed by 2 dimension dispersed wavelet transform. According to the characteristics of high-frequency and low frequency

some other informations are hidden into the two lowest bits of high-frequency

which is called data conceal. Adding harass applies to change lww-frequency so as to disturb quality of restored image. To distingUish image’s true and false

a procession called false prevention is ed to get some eminent sign in high-frenquency by altering some pixels’ value. Because these methods are based on image data processed by wavelet transform

there are approximately no other additional information. So image compression based on wavelet transform also can be used to these processed image.
