A robust blind watermarking method using quantization of distance between wavelet coefficients

Abstract

In this paper, we propose a robust blind watermarking algorithm based on quantization of distance among wavelet coefficients for copyright protection. We divide wavelet coefficients into someblocks and obtain the first, second, and thirdmaximum coefficients in each block. Then, we quantize the first and second maximum coefficients according to binary… (More)
