Comparative Studies of various Digital Image & Audio Watermarking Techniques IJTSRD
In this paper a brief review of various audio and image watermarking techniques has been carried out. Properties of both image and audio are different while processing. In this work a blind frequency masking algorithm for hiding the image data into audio signal using DCT is proposed. DCT provides compression & to avoid distortions from […]
DCT Based Robust & Secured Digital Image to Audio Watermarking Algorithm IJTSRD
In this paper, a new watermarking based on Discrete Cosine Transform Sub-band coding scheme is presented. This method uses the time domain signal & process it in frequency domain, while time domain features of the carrier remains same, so no one can identify the hidden data into it. The algorithm is based on Psychoacoustic Auditory […]
