Three-dimensional separable discrete wavelet transform (DWT).
dwt.3d(x, wf, J=4, boundary="periodic")
idwt.3d(y)
input array
name of the wavelet filter to use in the decomposition
depth of the decomposition, must be a number less than or equal to \(\log_2(\min\{X,Y,Z\})\)
only "periodic"
is currently implemented
an object of class dwt.3d
