Txdec
TX domain noise removal, 2- or 3-D
Txdec < in.H > out.H
window sizes in samples to calculate the
noise filters in. The noise and signal should
be stationary within these windows. =item k1,k2,k3 - integer
number of windows
PEF sizes (time,along w2,along w3)
Filter lags (time,along w2,along w3)
stabilization factor
defaults
a1=5,a2=2,a3=1 In-line or 2-D PEFs only.
For a 3-D PEF, use something like a2=2,a3=2.
Be warned, as the number of filter coefficients
increases, the run time increases by about
the cube of the number of filter coefficients.
w1=min(n1,20)
w2=min(n2,20)
w2=min(n3,6)
k1= 1.5 * n1/(w1-a1+1.)
k2= 1.5 * n2/(w2-a2+1.)
k3= 1.5 * n3/(w3-a3+1.)
lag1 = (a1/2)+1
if a3 is 1, then lag2 =(a2/2)+1, else lag2 = 1
lag3=1
