A threshold becomes a measurement
Change the segmentation threshold and pixel calibration. Inspect the largest connected object.
Observed intensity
Green: largest component · gray: other foreground
The exact synthetic 64 × 64 image from chapter 15. Foreground means intensity greater than or equal to the threshold; components use four-neighbor connectivity. Area = selected pixels × spacing². This toy object is not a medical image or a validated measuring instrument.
