BBOX

Python object: phenotypic.schema._bbox.BBOX

Extract bounding box coordinates and centroids of detected colonies.

Compute the axis-aligned bounding box and centroid (geometric and intensity-weighted) for each detected colony. These spatial measurements form the foundation for region-of-interest extraction, grid alignment assessment, and neighbor-distance calculations.

Category: Bbox

Column label	Description
Bbox_CenterRR	The row coordinate of the center of the bounding box.
Bbox_MinRR	The smallest row coordinate of the bounding box.
Bbox_MaxRR	The largest row coordinate of the bounding box.
Bbox_CenterCC	The column coordinate of the center of the bounding box.
Bbox_MinCC	The smallest column coordinate of the bounding box.
Bbox_MaxCC	The largest column coordinate of the bounding box.
Bbox_IntensityWeightedCenterRR	The intensity-weighted center row coordinate of the object (skimage centroid_weighted).
Bbox_IntensityWeightedCenterCC	The intensity-weighted center column coordinate of the object (skimage centroid_weighted).
Bbox_DistWeightedCenterRR	Row coordinate of the per-object Euclidean-distance-transform maximum (deepest interior point of the object mask). Robust to thin filamentous extensions that pull intensity-weighted centroids off-body.
Bbox_DistWeightedCenterCC	Column coordinate of the per-object Euclidean-distance-transform maximum (deepest interior point of the object mask). Robust to thin filamentous extensions that pull intensity-weighted centroids off-body.
