Sets the maximum allowable gap for inferring whether a face will never be seen again in the series of frames that are being processed by the detector. Default: 3
In video, a face may temporarily be undetectable in certain intermediate frames due to blurring associated with sudden camera movement or sudden extreme changes in lighting. This setting adds a tolerance, delaying onDone notification to the tracker during these temporary conditions.
maxGapFrames | tolerance, measured in number of frames received, for determining when a tracked item is no longer visible |
