Abstract

In this paper, we propose a new VQ steganographic method for embedding binary images and improving the stego-image quality. The main idea is using the new S-tree to represent the binary image and applying the genetic k-means clustering technique on the codebook to obtain strong cohesion clusters in order to reduce the replacement distortion. Experimental results show that our method outperforms the existing schemes on both image quality and embedding capacity.
