The objective of this study is to develop the image processing algorithm using stationary wavelet transform to get the normalized cropping images which would be suitable inputs processing and detection. Testing is done using a real-time visual recognition system. The Matlab software version 2010a is...
The stationary wavelet decomposition structure is more tractable than the wavelet one. So the utilities, useful for the wavelet case, are not necessary for the stationary wavelet transform (SWT). In this section, you'll learn to Load a signal Perform a stationary wavelet decomposition of a signa...

2.1. Lifting wavelet transform Lifting wavelet transform (LWT), proposed by Sweldens [22], is a new wavelet construction method using the lifting scheme in time domain. The main feature of the LWT is that it provides an entirely spatial domain interpretation of the transform, as opposed to ...
We have assessed the performance of our surrogate method by comparing our results with those obtained from a non-stationary surrogate algorithm based on discrete wavelet transform. Results confirm that, compared with stationary Fourier-based and non-stationary DWT-based surrogate algorithms, our method ...

InSST, an important parameter is the numberKof decomposed components. Further, since SST involves taking the wavelet (or short-time Fourier) transform of the signal, specifying related parameters, e.g., the mother wavelet (e.g., Morlet), the number of scales (frequencies), and\(\mu\)that...
