| 摘 要： | 自适应隐写用于将适量的消息比特嵌入到载体以取得感知质量和容量的最佳折衷.本文提出一种基于量化嵌入机制的自适应隐写方法,并基于该方法将秘密消息比特嵌入到由Hilbert填充曲线顺序构造的三像素组的两像素差中.由于充分利用图像本身的感知特性构造了量化嵌入使用的分割码本,所提算法在感知质量和容量上具有较好的综合性能.

| Abstract: | Adaptive steganography is to embed moderate message bits to gain the optimum trade-off between capacity and imperceptibility.In this paper,an adaptive steganographic method is proposed based on the quantization-based embedding mechanism.The message bits are embedded into triple-pixel differences constructed by the Hilbert curve scanning order through the proposed method.Because the partition codebook used in the quantization-based embedding phase is built up based on the perceptual characteristics,the propo... |
