An example of wavelet denoising using lazy transform and the lifting scheme

This paper considers the implementation of the lifting scheme. It is used as an effective and flexible tool for introducing signal dependence into the problem by improving the wavelet properties. Here, we present the results for simple example of the lazy transform implementation for the signal deno...

Description
Summary:This paper considers the implementation of the lifting scheme. It is used as an effective and flexible tool for introducing signal dependence into the problem by improving the wavelet properties. Here, we present the results for simple example of the lazy transform implementation for the signal denoising problem. The results are obtained by testing different threshold values.
