Process Using Region of Interest (ROI)

ImageGear allows you to specify a Region of Interest (ROI) as follows:

  • Specify rectangular ROI for nearly all image processing methods
  • Specify arbitrary ROI for most image processing methods (i.e., ellipse, polygon, and freehand)
  • Create 1-bit mask image for identifying which pixels to include/exclude from image processing algorithms

See ImGearROI Class, ImGearROIMask Class, and ImGearROIRectangle Class for more information.
