public MotionEstimatorAlgorithm()

Method Detail

requiredNumberOfFrames

protected int requiredNumberOfFrames()

The required number of frames required for the given motion estimation algorithm to work. The default is 1 which means the algorithm will only receive the previous frame. If more are required, override this method and return the required number.

Returns:

The required number of frames to pass to the algorithm.
