A digital watermarking algorithm for high capacity index image robust to format transformation

Based on the image edges non-changing characteristic in image format transformation, a new digital watermarking algorithm for huge index image is proposed. The watermarking information was embedded in edges by adjusting the edge pixels; therefore, the algorithm is robust against the lossless image f...

Description
Summary:Based on the image edges non-changing characteristic in image format transformation, a new digital watermarking algorithm for huge index image is proposed. The watermarking information was embedded in edges by adjusting the edge pixels; therefore, the algorithm is robust against the lossless image format transformation. The experimental results show that the proposed algorithm has perfect Robustness against the lossless image format transformation and good transparency.
