Public Constructors

public Builder (Detector<Face> detector, Tracker<Face> tracker)

Creates a LargestFaceFocusingProcessor builder.

Parameters

detector	detector instance which detects/tracks the associated face
tracker	tracker instance which receives events for the associated face

Public Methods

public LargestFaceFocusingProcessor build ()

Builds the LargestFaceFocusingProcessor instance.

public LargestFaceFocusingProcessor.Builder setMaxGapFrames (int maxGapFrames)

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.

Parameters

maxGapFrames	tolerance, measured in number of frames received, for determining when a tracked item is no longer visible
