Blemish Example #2
Blemish failure due to FM. The blue box and red circle are part of the annotated
image. Annotated images end with _BLEMISH in the file name. These annotations are
drawn by the analysis software and not part of the real image.
The blemish that is circled however is real and indicates FM or
a defect in the lens.
