Fx2d - 2D FX decon
Fx2d < in.H > out.H
window sizes in samples to calculate the noise filters in. The noise and signal should be stationary within these windows.
number of windows in each direction
PEF (prediction error filter) size.
stabilization factor
default w1=20, w2=10 noper=5 - 5 is generally good, less than 4 may produce poor answers, more than 7 wastes time, and the results are generally insensitive to values between 5 and 7. k1 = 1.5 * n1/(w1+1.) k2 = 1.5 * n2/(w2-noper+1.) lambda = 0.0 -- real data generally has enough noise to keep the process stable. Synthetic data may need a small lambda, say 0.001.
