Region of Interest (ROI) narrows down AI-based detections to only the principal area. For example: Suppose you want to focus on the handwash sink area to check for handwash compliance. In such a case, you do not need AI to monitor the whole room. Here, you can simply draw the area using the ROI tool. After this, the AI will detect handwash compliance in only the ROI instead of the entire screen thus, reducing computational costs.
