sobel() [1/2]

MAYAFLUX_API void MayaFlux::Kinesis::Vision::sobel	(	std::span< const float >	gray,
		std::span< float >	dx,
		std::span< float >	dy,
		std::span< float >	tmp,
		uint32_t	w,
		uint32_t	h
	)

Sobel gradient writing dx and dy into caller-supplied buffers.

Does not compute magnitude or angle. tmp is used as the horizontal filter pass scratch. All buffers must be size >= w * h and must not alias.

Parameters

gray	Input span, size w * h.
dx	Output horizontal gradient, size >= w * h.
dy	Output vertical gradient, size >= w * h.
tmp	Scratch span for separable filter pass, size >= w * h.
w	Image width in pixels.
h	Image height in pixels.
