[Insight-users] Noise simulation

[Oleksandr Dzyubak]

Dear ITK users,

Did anybody tested the noise simulation codes from the submission
"Noise simulation" http://hdl.handle.net/10380/3158 ?
The most needed (for me at least) noise generators
(Gauss and salt and pepper)
produce corrupted images with periodic line patterns
(see attached images). To generate those images, I followed
the parameter recommendations taken from the submission.

./gauss cthead1.tif cthead1_gauss_s22_8_m0.png 22.8 0
./sp cthead1.tif cthead1_sp_0016.png 0.016

Did anybody get similar results?
