二代小波harr变换整数小波变换，适合图像处理专业人员参考,Second generation wavelet transform Harr integer wavelet transform for image processing professionals reference

基于整数小波变换的图像可逆水印，很好用，可逆性很强，自己查找的资料(Image reversible watermarking based on integer wavelet transform is very useful. It has strong reversibility and finds information by itself.)
