Digital image watermarking means embedding information into image in such a way that it is imperceptible to a human observer, but can be easily detected by special computer algorithm. A digital watermark is a transparent, invisible information pattern that it is inserted into a suitable component of the data source by using a specific algorithm. Please note that this is one of a early research projects, with some format drawbacks and background experience lackage as well..

CAN i GET THE CODE FOR HIDING IMAGES IN AUDIO USING SPREAD SPECTRUM?

M, N are the size of each dimension of watermarked picture, Mb is a norm of M in correlation with size of single watermarked area (one of 64's), Nb is a norm of N in correlation respectively.

What is the meaning of Mb and [M/K] in the line 62

Originally implemented in 2009y.
