What is the difference between wavelets and framelets??

Does Discrete Wavelet Transform and Framelet have the same algorithm??

Answer 1

[Wayne King]

Yes and no.

The discrete wavelet transform is often used as synonymous with the discrete nonredundant (critically-sampled) wavelet transform.

Framelets are redundant wavelet transforms. The Wavelet Toolbox currently features the stationary wavelet transform and the nondecimated wavelet transform which are highly-redundant framelet transforms. There are framelet decompositions with less redundancy than those two.

The CWT as implemented in a computer is also a wavelet frame decomposition.
