Segment objects

Overview​

By default, for an image instance segmentation annotation task, H2O Label Genie offers a Box to polygon feature that enables you to improve the efficiency of manual labeling. A Box to polygon feature enables you to encapsulate an object class with a rectangular that is immediately replaced with a more complex polygon that captures all the borders of the object class inside the rectangular.
