Abstract
AbstractIn order to improve the capacity of image steganography scheme, a novel self-adaptive image steganography scheme, taking advantages of iterative blending and integer wavelet transform (IWT), is proposed in this chapter. The employment of IWT resolves the problems of boundary difference and rounding difference of image steganography scheme based on traditional wavelet transform. Moreover, human visual model (HVS) is adopted to effectively make a trade-off between imperceptibility and robustness. Experimental results demonstrate that the proposed scheme has excellent properties of invisibility and robustness, furthermore, the adoption of iterative blending technique highly improves the hiding capacity of the proposed scheme.KeywordsIterative BlendingInteger Wavelet Transform (IWT)Image Steganography SchemeRound DifferenceImperceptibilityThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
