In 2010, Chen et al. proposed a data hiding scheme with high payload and good visual quality. The edge information is detected and most of the secret bits are embedded into the edge area. An index pixel is chosen to record the edge information for each block. However, the embedding space will decrease because of the index pixel. Thus, we proposed a data hiding that enhances the visual quality based...
We propose an effective data hiding method based on the EMD embedding scheme proposed by Zhang et al. in order to enhance the embedding capacity. The main idea of our proposed scheme is to convert secret binary messages into a sequence of digits in an 8-ary notational system. Each secret digit is embedded into two cover pixels by modifying the least significant bits (LSBs). As the experimental results...
