gaussian_blur() [2/2]

MAYAFLUX_API std::vector< float > MayaFlux::Kinesis::Vision::gaussian_blur	(	std::span< const float >	src,
		uint32_t	w,
		uint32_t	h,
		float	sigma
	)

Separable Gaussian blur.

Kernel radius is ceil(3 * sigma). Kernel is normalised to unit sum. Decomposes into horizontal and vertical 1D passes via filter_separable.

Parameters

src	Single-channel float span, size must be w * h.
w	Image width in pixels.
h	Image height in pixels.
sigma	Standard deviation in pixels. Must be > 0.

Returns

Blurred float vector of length w * h.
