Description: This paper presents a steganography method based on an embedded zerotree wavelet compression scheme and bitplane complexity segmentation steganography.The proposed steganography enables us to use lossy compressed images as dummy files in bit-plane-based steganographic algorithms.Large embedding rates of around 25 of the compressed image size were achieved with little noticeable degradation in image quality-This paper presents a steganography method based on an embedded zerotree wavelet compression scheme and bitplane complexity segmentation steganography.The proposed steganography enables us to use lossy compressed images as dummy files in bit-plane-based steganographic algorithms.Large embedding rates of around 25 of the compressed image size were achieved with little noticeable degradation in image quality

Description: 基于图像复杂度的隐写方法研究 为了提供较大的隐写容量和保持良好的载密图像质量,依据人眼对纹 理、边界和黑暗区域变化敏感性弱的视觉特点,结合小波变换提出了一种图像复杂度描述方法,将图像小块分为纹理、边界、黑暗和平滑四个不同类别,利用模函数 设计隐写算法,在不同区域嵌入不同量的信息.实验结果表明,新的复杂度描述方法能准确区分不同类型的小块,隐写算法在提高嵌入容量的同时保持了较好的视觉 质量. -Study steganographic method based on image complexity in order to provide greater capacity and maintain good steganography stego image quality, according to the human eye textures, borders and change the sensitivity of dark areas weak visual features, combined with a wavelet transform is proposed described method of image complexity, the image is divided into small pieces texture, borders, dark and smooth four different categories, use the function module design steganography, embedding different amounts of information in different areas. the experimental results show that the new complexity described method can accurately distinguish between different types of pieces, steganography to improve the embedding capacity while maintaining good visual quality.
