| Popis: | This work focuses on the problem of maximum watermarking payload under the condition of keeping image transparency. The maximum watermarking payload of JPEG images is influenced by internal factors such as the size, complexity and visual sensitivity of images, as well as external factors including embedding operators, carrier frequency bands and embedding intensity, etc. Through the construction of payload mathematical model, theoretic analysis and experimental derivation we propose an estimation method of maximum watermarking payload based on the DCT coefficients. The feasibility and efficiency of the proposed method has been demonstrated in our experiments by adopting two embedding operators and three carrier frequency bands. Our results show, in comparison with previously related work, the proposed method can be more practical. |
