Abstract
A graphics card of a computer system is configured to detect watermarks within a video signal that includes one or more windows of a display. The frames of the video signal are analyzed to locate image areas in which the video signal changes, and a bounding box around these areas of change is defined as an area(s) of interest. Watermark detection is then performed within the area(s) of interest.
