Good day non-name,
once more it turns out that it is really helpful to know what someone is
"really trying to achieve".
Now that we know a bit more about the goal, I fully agree with Karsten
that you should give the "Polar Transformer"-plugin a try. It transforms
concentric circles into straight lines, i.e. imperfect circles into
wiggly lines. In the transformed image you can then project rectangular
selections in order to obtain measures for the local/regional deviation
from a perfect circle...
Best
Herbie
