摘要: In this paper we engage in AWGN watermark for grayscale image (the message is embedded by adding of white Gaussian noise matrix; detection blind, correlation based). We search criteria ``the best'' (minimal one which guaranties detectability) embedding strength robust against expected attack. These find watermarks, are spatial or transform domains; bit a longer message; into whole some its coefficients. This peculiarity that do not propose new watermarking algorithm; well known, algorithm the best watermark.
