Hi,
I think I address this question mainly to Steve Smith, the author of Susan
filter.
I have a student, who is implementing Susan smoothing filter using ITK
(www.itk.org) image processing library. In trying to understand FSL
implementation he studied susan_smooth.c. However, he can not figure out, how
were some constants determined:
a) 10000 at lines 386, 387 and 390
b) 100 at lines 427, 428, 431
c) 1000000 at lines 699, 700 and 703
d) 20000 at lines 966 and 1156
e) 200 at lines 1036 and 1230
f) 2000000 at line 1363
These constants are always used near-by
if ( use_median ), so I assume the logic is similar.
I would appreciate your explanation. Thanks in advance.
Cheers,
Martin
