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...

Key-dependency for a wavelet-based blind watermarking algorithm
When a host image is watermarked multiple times by the same algorithm collisions can occur. This makes it difficult for an image to host multiple watermarks. But this hosting is n...

An Architecture Design of Threshold-Based Best-Basis Algorithm
The best-basis algorithm has gained much importance on textured-based image compression and denoising of signals. In this paper, an architecture for the wavelet-packet based best-...

A Rearrangement Algorithm of Wavelet Packet Coefficients for Zerotree Coding
Zerotree coding based on the wavelet transform is a very effective image compression technique. Since it exploits the dyadic multiresolution characteristic of wavelet transform, h...
