Efficient Self-Adaptive Image Steganography Scheme Based on Iterative Blending and Integer Wavelet Transform

摘要

In this chapter, taking advantages of iterative blending, the human visual masking characteristic and IWT, a self-adaptive image steganography is proposed. The proposed scheme has the following properties:1. The employment of IWT resolves the problems of boundary difference and rounding difference of image steganography scheme based on traditional wavelet transform.2. Using visual model to select the optimal embedding positions and embedding strength and the ideal compromise between imperceptibility and robustness is obtained.3. The large hiding capacity of transform domain is realized.
