SIZE#

Python object: phenotypic.schema._size.SIZE

Measure colony area and integrated intensity as lightweight size proxies.

Extract two fundamental size metrics per detected colony: pixel area (biomass extent) and integrated grayscale intensity (total brightness, a proxy for optical density). This is a convenience class for rapid size assessment without the overhead of full shape or intensity statistical analysis.

Description

Type

Size_Area

Total number of pixels occupied by the microbial colony.Larger areas typically indicate more robust growth or longer incubation times.

Tier 1 · Direct phenotype

Size_IntegratedIntensity

The sum of the object’s grayscale pixels. Calculated as \(\sum{\text{pixel values}} \times \text{area}\).
