Robustness Analysis of Blind and Non-Blind Multiple Watermarking using Edge Detection and Wavelet Transforms

摘要

In this paper we analyse the robustness of both blind and non-blind multiple watermarking methods in color images using Haar, Daubechies and Biorthogonal wavelets. The embedding process uses a canny edge detection method and hides the watermark with the perceptual considerations on different modalities of images. The extraction scheme uses blind and nonblind methods to retrieve the watermark. The more number of attacks are simulated in the watermarked image to analyse the robustness and prove the authenticity of the digital content.
