Digital Image Watermarking Program

Abstract:

This paper proposes digital image watermarking algorithm in DCT domain which makes use of the unique nature of chaotic sequences to encrypt binary image watermarking with copyright information via chaotic sequences and then embeds watermarking component of different strengths in DCT domain of different image blocks self-adaptively. Through the added Gaussian noise, salt and pepper noise and JPEG compression and shear processing operations, the results show that the algorithm has a good visual masking and robustness.
