Audio signal encryption using chaotic Hénon map and lifting wavelet transforms
We propose a new audio signal encryption scheme based on the chaotic Hénon map. The scheme mainly comprises two phases: one is the preprocessing stage where the audio signal is transformed into a data by the lifting wavelet scheme and the other in which the transformed data is encrypted by chaotic data set and hyperbolic functions. Furthermore, we use dynamic keys and consider the key space siz...
متن کاملFlexible Wavelet Transforms Using Lifting
Roger L. Claypoole, Jr. and Richard G. Baraniuk, Rice University Summary We introduce and discuss biorthogonal wavelet transforms using the lifting construction. The lifting construction exploits a spatial{domain, prediction{error interpretation of the wavelet transform and provides a powerful framework for designing customized transforms. We discuss the application of lifting to adaptive and n...
متن کاملWavelet transforms via lifting
Ramesh Neelamani December 23, 1998 Project Advisor: Prof. C.S. Burrus ELEC 696 Project Department of Electrical and Computer Engineering, Rice University, Houston, TX 77005. [email protected] Abstract Lifting has traditionally been described in the time/spatial domain and the intuition behind the entire scheme holds in this domain. It is known that the lifting scheme, as conventionally desc...
متن کاملInteger Wavelet Transforms using the Lifting Scheme
Due to its good decorrelating properties, the wavelet transform is a powerful tool for signal analysis. The lifting scheme is an efficient algorithm to calculate wavelet transforms and it allows for the construction of second-generation wavelets. Furthermore it can easily be converted to an integer transform, which is of great importance for multimedia applications. We show how the lifting sche...
متن کاملAdaptive wavelet transforms via lifting
This paper develops two new adaptive wavelet transforms based on the lifting scheme. The lifting construction exploits a spatialdomain, prediction-error interpretation of the wavelet transform and provides a powerful framework for designing customized transforms. We use the lifting construction to adaptively tune a wavelet transform to a desired signal by optimizing data-based prediction error ...
