When I useed Mathematica,If found many Transforms in the list of Discrete Wavelet Transforms.
- discrete wavelet transform (DWT)
- stationary wavelet transform (SWT)
- lifting wavelet transform (LWT)
- discrete wavelet packet transform (DWPT)
- stationary wavelet packet transform (SWPT)
I always use DWT,and found it can be used in many cases such as de-noising,filtering data,embedding watermarking,detecting the discontinuity and so on.
Is it different cases use different transforms?So how to know it?
