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.

   * - ``Bbox_CenterCC``
     -  The column coordinate of the center of the bounding box.

   * - ``Bbox_IntensityWeightedCenterRR``
     - The intensity-weighted center row coordinate of the object (skimage ``centroid_weighted``).
     - :bdg-ref-muted:`Identity / design <measurement-classification>`
   * - ``Bbox_IntensityWeightedCenterCC``
     - The intensity-weighted center column coordinate of the object (skimage ``centroid_weighted``).
     - :bdg-ref-muted:`Identity / design <measurement-classification>`
   * - ``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.
