Abstract

Aim at the grayscale image watermarking embedding and detection, on the basis of introduction of digital watermarking principle and wavelet multiresolution analysis, adaptive blind grayscale image watermarking algorithm based on wavelet analysis is put forward. Firstly, the embedded watermarking signal is processed by spread spectrum technology, secondly… (More)
