A coverless image steganography based on robust image wavelet hashing
Since the concept of coverless information hiding was proposed, it has been greatly developed due to its effectiveness of resisting the steganographic tools. In this paper, a new coverless steganography is presented to hide the secret data in a more…

Hand gesture recognition using discrete wavelet transform and hidden Markov models
Gesture recognition based on computer-vision is an important part of
human-computer interaction. But it lacks in several points, that was image brightness, recognition time, and accuracy. Because of that goal of this research was to create a hand…
