Edge Tolerance 5px

Ignores colonies touching the crop boundary.

Contrast Boost (CLAHE) 3.0

Helps separate faint colonies from background.

Threshold Block Size 101

Size of pixel neighborhood for local thresholding.

Threshold C (Light Plates) 15

Threshold C (Dark/UV Plates) -15

Area Filter (pixels)

Petri Dish Diameter (mm)

Real-world size. Standard is 90mm. Used to calculate morphology stats in mm.

Watershed Split Force 0.5

Higher value splits tightly clustered colonies more aggressively.

Sharpen (Unsharp Mask) 0

Corrects blurry/out-of-focus images. 0 = off.

Min Circularity 0.3

1.0 is a perfect circle. Lower values allow clusters.
