region of interest (ROI)

Region of Interest (ROI) is the area of a photo or graph that is of particular interest. The region of interest can be a specific section of an image or a section of a graph that needs to be evaluated for certain events.

ROI technology can be used in medicine to detect a tumor on an X-ray image, as well as to evaluate the faces of a crowd of people or to provide a detailed view of recorded traffic situations. In all ROI applications, the goal is to allow the viewer to look at, evaluate and analyze image details in more detail using image processing. The advantage can be seen in the fact that bandwidth can be saved and the frame rate increased when evaluating a section of the image.

The ROI area can be displayed with a higher resolution and thus better evaluated.
