Input parameters
Documentation illustration (illustration unavailable in the archive). Image Src : class, type accepted U8 and I16.
Documentation illustration (illustration unavailable in the archive). ROI Descriptor : cluster, descriptor that defines the region of interest.

Documentation illustration (illustration unavailable in the archive). Contours : array, are each of the individual shapes that define the ROI.
Documentation illustration (illustration unavailable in the archive). ID : enum, refers to whether the contour is the external or internal edge of an ROI.
Documentation illustration (illustration unavailable in the archive). Type : integer, is the shape type of the contour.
Documentation illustration (illustration unavailable in the archive). Coordinates : array,indicates the relative position of the contour.
