FUNCTIONFarnebackOpticalFlow_create
RETURN TYPEFarnebackOpticalFlow | null
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Create an owned FarnebackOpticalFlow instance with the supplied configuration.

Class computing a dense optical flow using the Gunnar Farneback's algorithm.
