2L-DWTS — Steganography technique based on second level DWT

2016 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2016
Steganography is a technique used to communicate a secret message secretly hidden in an innocuous cover. In this paper, a new image steganography technique 2L-DWTS is proposed. This technique, 2L-DWTS embeds secret message in the higher frequency components among the second level DWT components of the cover image.

The DWT Group Fingerprinting Scheme

2014 IEEE 12th International Conference on Dependable, Autonomic and Secure Computing, 2014
With the development of network and multimedia technique, the transfer of multimedia content becomes popular. The relations between distributors get hierarchical and diversified. As far as digital wholesale and retail are concerned, the traditional fingerprint which helps traitor tracing cannot achieve effective tracing of colluding middlemen ...

The double-density dual-tree DWT

IEEE Transactions on Signal Processing, 2004
This paper introduces the double-density dual-tree discrete wavelet transform (DWT), which is a DWT that combines the double-density DWT and the dual-tree DWT, each of which has its own characteristics and advantages. The transform corresponds to a new family of dyadic wavelet tight frames based on two scaling functions and four distinct wavelets.

A common architecture for the DWT and IDWT

Proceedings of International Conference on Application Specific Systems, Architectures and Processors: ASAP '96, 2002
This paper presents an architecture which is equally efficient at computing both the discrete wavelet transform (the DWT) and the inverse discrete wavelet transform (the IDWT). Given the seemingly fundamental difference between the structure of a DWT filter bank and the structure of an IDWT filter bank, it is somewhat surprising that such an ...
