Dear AFNI team,
I am looking to downscale an image (PET, BOLD) to a lower resolution in order to match images with a lower resolution and SNR.
I am using images from different species, scanned with different machines, with very different SNRs.
Can you think of a meaningful way of downscaling a high resolution/SNR image to match an image at a lower resolution and SNR that would make them more "comparable"?
I guess smoothing would be a step, but would not really add noise to the high-resolution/SNR image.
Thank you in advance!
Clément
