extract()

void MayaFlux::Yantra::Vision::VisionMatrix::extract	(	const Kinesis::Vision::VisionAnalysis &	analysis,
		const std::shared_ptr< Core::VKImage > &	image
	)

Extract from image with analysis and keep all three until the next call.

analysis() and frame() return analysis and image, extraction() what the extractor produced. The analysis may come from another frame.
