用小波进行图像处理，以及一个QPSK调制程序，还有用MATLAB实现二维小波分解与重构程序，请大家指正-wavelet image processing, and a QPSK modulation procedure, there are two-dimensional MATLAB wavelet decomposition and reconstruction process, please correct

16QAM调制和借条方法，以及利用小波变换隐藏16QAM调制后生成的图片信息，接收端进行图片的处理，并提取嵌入信息-16QAM modulation and IOU methods, and the use of wavelet transform to hide after 16QAM modulation generated image information, the receiver for processing images and extracting embedded inform
