hi,
I want to know if there is any optimal value for the parameter PSNR.
I hav implemented an algorithm for datamarking in which for a message
embedd of 629 bytes in a bmp image,a psnr value of 68db is obtained and
for a message embed of 4.43kb inside the same image, the psnr value is
49 db.I am a bit confused regarding this. Can the PSNR be higher as 69
db??
waiting for reply,
regds,
rukmani.
