抽取子图像: 通过一个随机混沌标签序列从原图像中抽取 对子图像加密:小波变换 ,在高频部分加密 重构原图，把加密好的子图像重新放回到原图像中 -from sub-images : a random chaotic sequence label from the original image from a tradition image encryption : wavelet transform, the high-frequency part of remodeling the

信息隐藏 给予二维离散小波变换的图象水印嵌入

实现图像小波变换,同一个窗口内分别实现原图和变换后的图像(Realize image wavelet transform, within the same window, the original image is implemented and after the transformation of the image)

关于图象消噪,基于小波分析的,希望有用,已经通过编译,效果还不错,(About image de-noising based on wavelet analysis, hope to useful, already by compiling, effect is good,)
