Smoothing of dynamic PET images in ECAT 6.3 and 7 format.

which are selected based on the MRL (maximum run length) and AUC difference.
Usage:

Example:
imgdysmo b00123dy1.img b00123dy1smoothed.img
Options:
-m=<3|5>
Set filter mask to 3x3x3 or 5x5x5 pixels (default)
-s=<1|2|3|4|5>
Set smoothing strength: 1=min, 2=default, 5=max
-a=<nr>
Set the nr of pixels to average inside smoothing mask;
by default this is set automatically based on the mask size
