用于实现图像的离散2维小波变换，图像可用于实现隐藏-Used to image two-dimensional discrete wavelet transform, the image can be used to achieve hidden

小波去噪,以及小波的db4和db7小波变换对图像的变换研究。-Wavelet de-noising and wavelet transform the db4 and db7 wavelet transform research on image.

未使用matlab小波函数实现图像的二维小波分解和重构，分解和重构结果有对比-Matlab wavelet function is not used to achieve a two-dimensional image wavelet decomposition and reconstruction, decomposition and reconstruction contrasting results

通过matlab可以实现图像融合，小波变换，希望有所帮助-By matlab can achieve image fusion, wavelet transform, hope that helps
