Picket Fence Test Question


I’m using the picket fence module to analyze EPID images on both HDMLC and Millennium MLC’s.

The output from the HDMLC images look more like I would expect them to, with blue points where I expect leaf stopping positions to be.

The output from Millennium images look different, though, with some blue points seemingly missing.

See attached images for screen captures in each case

Is there a way to tell if all the leaves are being detected? If they are being missed on the millenniums, is there a likely cause as to why?

Based on the error plot below they seem to be detected. Is it consistent when zooming in and out? matplotlib can sometimes be finicky when zoomed way out.
