Get the rms from the restored map in an
"intelligent" fashion.
Synopsis
get_rms(im)
Description
Get the rms from the restored map in an "intelligent" fashion. The
way this algorithm works is to first get the rms using the entire
image and then create a mask, using pixels in the image within -3 to 3
times the rms just calculated. The algorithm then iterates in this
fashion until the fractional difference between the previously
calculated rms and the currently calculated rms is below some
threshhold, currently hard wired to be 0.001.
Arguments
im
A valid image tool from which to get the rms
Allowed:
Any valid image tool
Default:
None
Returns
Float
Example
- include 'imagerpositiontest.g';
- ipt := imagerpositiontest();
- include 'image.g';
- myim := image('some.image');
- rms := ipt.get_rms(myim);
# numerous messages from image.stats() here
# and finally
- rms;
0.00384885306
