[Insight-users] Joint Histogram same "appearance" number of samples MI Bspline

[Emma Saunders]

Hi I'm performing some Bspline registration and have looked on the list to
find this information give regarding the number of samples.

   The number of samples to take must be enough
         for producing the same "appearance" of the joint histogram


I have plotted the joint histogram but not sure what the same
appearance means, how do I estimate the number of samples to use from
the joint histogram?


As an aside what drives the number of grid nodes to use, is it simply
the detail in the image, the amount of motion?


Thanks for any help


Emma
