imroi class

Region-of-interest (ROI) base class

Description

The imroi class is an abstract base class that specifies the Image Processing Toolbox™ interface for working with regions of interest (ROIs). You can use classes that inherit from the imroi interface to create interactive ROIs over an image.

The imroi class is a handle class.

Class Attributes

Abstract

true

For information on class attributes, see Class Attributes (MATLAB).

Creation

The imroi class is abstract, and creating an instance of the imroi class is not allowed. To learn how to create an ROI object from a concrete subclass of imroi, see imellipse, imfreehand, imline, impoint, impoly, or imrect.

Properties

Deletable — ROI can be deleted

true (default) | false

ROI can be deleted, specified as true or false.
