Abstract:
1. A method for rejecting information using a mobile device, the method comprising: obtaining a video frame using a camera coupled to the mobile device; detecting an at least one portion of the video frame at least partially representing a feature; identifying a first shift associated with the at least one portion of the video frame; identifying a second shift associated with an entire video frame, wherein the second shift associated with the entire video frame is identified using motion calculated from portions of the video frame that are distinct from the at least one portion of the video frame; determining a disparity between the first shift and the second shift; determining flickering in a detection of the feature by determining that the disparity is higher than a predetermined threshold; and rejecting the at least one portion of the video frame at least partially representing the feature as a false positive detection due to flickering.
