filter_separable() [1/2]

MAYAFLUX_API void MayaFlux::Kinesis::Vision::filter_separable	(	std::span< const float >	src,
		std::span< float >	tmp,
		std::span< float >	dst,
		uint32_t	w,
		uint32_t	h,
		std::span< const float >	kernel_x,
		std::span< const float >	kernel_y
	)

Separable 2D filter writing into caller-supplied buffers.

Horizontal pass writes into tmp, vertical pass writes into dst. All three spans must be size >= w * h and must not alias each other.

Parameters

src	Input span, size w * h.
tmp	Scratch span for horizontal pass, size >= w * h.
dst	Output span, size >= w * h.
w	Image width in pixels.
h	Image height in pixels.
kernel_x	Horizontal 1D kernel, odd length.
kernel_y	Vertical 1D kernel, odd length.

    convolve_horizontal(src, tmp, w, h, kernel_x);
    convolve_vertical(tmp, dst, w, h, kernel_y);
