edges()

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

source kept where analysis.detect_edges reaches the edge threshold, transparent elsewhere.
