[Insight-users] statistics on two groups of image volumes

[Luis Ibanez]

Hi Dennis,

Could you please give us more details on what you are trying
to do.


I would assume that you have a collection of images and that...

you want to compute the average intensity of all the images ?

or the standard deviation of the intensities of the homologous
pixel across the images ?

Are the images of the same size ?

Are the images registered ?

Are you talking about 2 images ? 10, 200, 2000 ?


Depending on the scenario that you have in mind, different
options available in ITK could apply.


Please give us a more detailed description of what you
are attempting to do.


     Thanks


       Luis
