◆ SimdMedianFilterRhomb3x3()

void SimdMedianFilterRhomb3x3	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs median filtering with a 3x3 rhomb window for an 8-bit interleaved image.

The filter is applied independently to every channel. Border pixels are handled by nearest-pixel replication. The rhomb window contains 5 samples: top, left, center, right and bottom. The output is the middle value of these 5 samples.

Note: This function has a C++ wrapper: Simd::MedianFilterRhomb3x3(const View<A>& src, View<A>& dst).

Parameters

[in]	src	- a pointer to pixels data of original input image.
[in]	srcStride	- a row size of src image (in bytes).
[in]	width	- an image width.
[in]	height	- an image height.
[in]	channelCount	- a number of 8-bit channels per pixel.
[out]	dst	- a pointer to pixels data of filtered output image.
[in]	dstStride	- a row size of dst image (in bytes).

◆ SimdMedianFilterRhomb5x5()

void SimdMedianFilterRhomb5x5	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs median filtering with a 5x5 rhomb window for an 8-bit interleaved image.

The filter is applied independently to every channel. Border pixels are handled by nearest-pixel replication. The rhomb window contains 13 samples. The output is the middle value of these 13 samples.

Note: This function has a C++ wrapper: Simd::MedianFilterRhomb5x5(const View<A>& src, View<A>& dst).

Parameters

[in]	src	- a pointer to pixels data of original input image.
[in]	srcStride	- a row size of src image (in bytes).
[in]	width	- an image width.
[in]	height	- an image height.
[in]	channelCount	- a number of 8-bit channels per pixel.
[out]	dst	- a pointer to pixels data of filtered output image.
[in]	dstStride	- a row size of dst image (in bytes).

◆ SimdMedianFilterSquare3x3()

void SimdMedianFilterSquare3x3	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs median filtering with a 3x3 square window for an 8-bit interleaved image.

The filter is applied independently to every channel. Border pixels are handled by nearest-pixel replication. The output is the middle value of 9 samples in the 3x3 window.

Note: This function has a C++ wrapper: Simd::MedianFilterSquare3x3(const View<A>& src, View<A>& dst).

Parameters

[in]	src	- a pointer to pixels data of original input image.
[in]	srcStride	- a row size of src image (in bytes).
[in]	width	- an image width.
[in]	height	- an image height.
[in]	channelCount	- a number of 8-bit channels per pixel.
[out]	dst	- a pointer to pixels data of filtered output image.
[in]	dstStride	- a row size of dst image (in bytes).

◆ SimdMedianFilterSquare5x5()

void SimdMedianFilterSquare5x5	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs median filtering with a 5x5 square window for an 8-bit interleaved image.

The filter is applied independently to every channel. Border pixels are handled by nearest-pixel replication. The output is the middle value of 25 samples in the 5x5 window.

Note: This function has a C++ wrapper: Simd::MedianFilterSquare5x5(const View<A>& src, View<A>& dst).

Parameters

[in]	src	- a pointer to pixels data of original input image.
[in]	srcStride	- a row size of src image (in bytes).
[in]	width	- an image width.
[in]	height	- an image height.
[in]	channelCount	- a number of 8-bit channels per pixel.
[out]	dst	- a pointer to pixels data of filtered output image.
[in]	dstStride	- a row size of dst image (in bytes).

◆ MedianFilterRhomb3x3()

void MedianFilterRhomb3x3	(	const View< A > &	src,
		View< A > &	dst
	)

Performs median filtering with a 3x3 rhomb window for an 8-bit interleaved image.

The filter is applied independently to every channel. Border pixels are handled by nearest-pixel replication. The rhomb window contains 5 samples: top, left, center, right and bottom. The output is the middle value of these 5 samples.

The source and destination images must have the same width, height and format (8-bit gray, 16-bit UV, 24-bit BGR/RGB or 32-bit BGRA/RGBA).

Note: This function is a C++ wrapper for function SimdMedianFilterRhomb3x3.

Parameters

[in]	src	- an original input image.
[out]	dst	- a filtered output image.
