filter_separable() [2/2]

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

Apply a separable 2D filter via two 1D passes.

Applies kernel_x horizontally then kernel_y vertically. Both kernels are applied with clamp-to-edge border handling.

Parameters

src	Single-channel float span, size must be w * h.
w	Image width in pixels.
h	Image height in pixels.
kernel_x	Horizontal 1D kernel. Length must be odd.
kernel_y	Vertical 1D kernel. Length must be odd.

Returns

Filtered float vector of length w * h.
