Object Programming: Annotating an Object Display |
|
A region of interest (ROI) is an area of an image defined for further analysis or processing. ROIs can be defined programmatically and interactively. The XROI utility lets you interactively define single or multiple regions from an image using the mouse. The utility displays defined ROIs and can output ROI data to specified ROI objects. Any ROI object, whether defined programmatically or interactively, can undergo further processing as an analysis-oriented IDLanROI object, or can be used for display as an IDLgrROI object.
See Regions of Interest under the functional category, Image Processing for a list or ROI creation and manipulation routines. Also see Working with Regions of Interest (ROIs) for extensive examples.
