The ROI element allows you to define a Region of Interest (ROI) - subset of data fully contained within a larger source region. You can define ROI for input and output data.
For example, you have 640x480 input image and want to process a 320x240 ROI that corresponds to the top left quadrant of the 640x480 source region. In your workspace it will look like this:
The ROI element has the following properties:
- X Offset - The X offset of the top left corner of the ROI.
- Y Offset - The Y offset of the top left corner of the ROI.
- Width - The ROI width.
- Height - The ROI height.
