label_id

uint32_t MayaFlux::Kinesis::Vision::Contour::label_id { 0 }

1-based label id of the component this contour traces, matching ComponentResult::boxes and BoundingBox::label_id numbering, and the value written per pixel in ConnectedComponents' device label buffer.

0 for a hole contour: a hole has no foreground pixels of its own to select by label, it is already absent from the label buffer wherever it opens through the parent's silhouette.
