OFDM_4QAM_R14

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.

a watermarking project that implemented in Matlab (Simulink). use a WAV file for input and address a output WAV file to save result ,
