Hey I am doing a MATLAB project on audio steganography . Which type of format mp3 , wav or cda would be most suitable for this . Also which stego technique should I go for ? Can you point out some online resources where I could find example codes for audio steganography ? My email ID is varun2k7dce@gmail.com . Looking forward to hearing from you
Hi... I'm doing project on image steganography based on wavelet transform to increase the embedding capacity and also to maintain good PSNR... I'm finding it more difficult to implement... Please, help me... :)
