Abstract
When multiple display screens share data from different control units, the screens may flicker or have other anomalies when the control units are not synced. A system and method for detecting flickering or other anomalies includes receiving a video feed of a display screen to be tested, recording, from the video feed, a video file of a predetermined length that includes a plurality of frames, selecting a region of interest in a frame of the video file to define a template image; and performing a pattern matching between the template image and a pattern image of respective frames in the video file to detect anomalies.
