Forensic has the option to process only a selected area--or "region of interest" (ROI)--of the original video. This is useful to improve processing speed, and can also allow the enhancement algorithms to generate better results in a limited area when the video frame contains significant light and color variations.
The ROI can be moved and resized using the corners when the ROI tool is selected. For more accurate control use the options available in the ROI filter
Left - Top left corner pixel location on the X-axis
Top - Top left corner pixel location on the Y-axis
