Abstract :
The aim of steganography is to hide huge information in a small media with robustness and invisibility. The main idea of this paper is to utilize a threshold mechanism to embed as much information of the secret image into the cover image as possible. The proposed threshold mechanism is setup especially to fit the human visual system. The experimental results show that the proposed human visual system has improved the quality in terms of perceptibility. On the hiding capacity issue, the proposed method has capability to embed a secret image in a cover image which its size is three times or more than the size of cover image.
