motion_mask()

std::shared_ptr< Core::VKImage > MayaFlux::Yantra::VisionExtractor::motion_mask	(	const std::shared_ptr< Core::VKImage > &	source,
		const Kinesis::Vision::VisionAnalysis &	analysis,
		uint32_t	source_w,
		uint32_t	source_h
	)

source kept where analysis.estimate_motion moves faster than the motion limits with enough confidence.

Null when no flow was computed or motion_activity is below the activity limit.
