An Improved Algorithm of Digital Watermarking Based on Wavelet Transform
In this paper, a digital image watermarking technique based on Discrete Wavelet Transform (DWT) will be proposed. This scheme is designed utilizing principles deriving from the hu...

Watermark Security via Secret Wavelet Packet Subband Structures
Abstract. Wavelet packet decompositions generalize the classical pyramidal wavelet structure. We use the vast amount of possible wavelet packet decomposition structures to create a...

Very fast watermarking by reversible contrast mapping
—Reversible contrast mapping (RCM) is a simple integer transform that applies to pairs of pixels. For some pairs of pixels, RCM is invertible, even if the least significant bits...

Efficient coherent phase quantization for audio watermarking
The weighted overlap add (WOLA) technique is routinely used in audio processing to avoid introducing audible clicks. This process introduces inter-dependencies between WOLA coeffi...
