Ungroup ROI
Description
Separates an ROI descriptor describing many contours into an array of ROI descriptors. Each of the ROI descriptors returned contains a single contour. Type : polymorphic.
Input parameters
ROI Descriptor : cluster, descriptor that contains multiple contours.
Global Rectangle : array, minimum rectangle required to contain all of the contours in the ROI. Rectangles are specified by their bounding rectangle, with the format (Left/Top/Right/Bottom).
Contours : array, are each of the individual shapes that define an ROI.
ID : enum, refers to whether the contour is the external or internal edge of an ROI.
Type : integer, is the shape type of the contour. Coordinates : array, indicates the relative position of the contour.
Output parameters
ROI Descriptors : array, returned array of ROI descriptors. Each ROI descriptor contains a single contour.
Global Rectangle : array, contains the coordinates of the bounding rectangle. Rectangles are specified by their bounding rectangle, with the format (Left/Top/Right/Bottom). Contours : array, are each of the individual shapes that define an ROI.
ID : enum, refers to whether the contour is the external or internal edge of an ROI.
Type : integer, is the shape type of the contour. Coordinates : array, indicates the relative position of the contour.
