OBJECT
======

Python object: ``phenotypic.schema._object.OBJECT``

Per-object identifier shared by every measurement table.

``Object_Label`` is written as the first column of every per-object
measurement DataFrame and serves as the per-image primary key that the
pipeline merges measurers on. Each detected colony in a plate image is
assigned a unique integer label, so size, shape, intensity, and color
measurements for the same colony line up row-for-row across operators when
joined on this column.

     - Integer label uniquely identifying each detected object (colony) within its source image. Acts as the per-image primary key shared by every measurement table, letting all per-colony measurements be joined together and traced back to a single colony on the agar plate.
