imgshrink - tpcclib 0.8.0 © 2023 by Turku PET Centre
Shrink the size of a dynamic or static PET image to take less memory and
disk space, and to reduce noise and computation time when testing
pixel-by-pixel modeling methods.
Eight neighbouring pixels are averaged into one pixel; thus image size
will be shrunk into 1/8 of the size of the original image.
ECAT 6.3, 7.x, and Analyze 7.5 and NIfTI-1 formats are accepted.
