Runa and Zhengyu,

If you are referring to my iterative deconvolution plugin, it is PSF-
based, not blind.  The last few parameters are things you experiment  
with until you get results you like.  One of the parameters is the  
number of iterations.  Several people have pointed out, and I have  
found in my own experience, that the results get worse if you iterate  
too many times.  The suggestion is to try a few values and see what  
works best.  The last checkbox, about dB, is only for acoustics.  Do  
not check it.
