[Insight-users] Re: LaplacianImageFiler

Hi Bing,

There is no reason for using the RescaleImageFilter
if you want to keep the same range of intensities.
This will be like a NULL filter, or an identity
operation.

Could you give us more details on why do you want to
do this ?


   Thanks


     Luis
