Function Documentation

SimdOperationBinary8u()

void SimdOperationBinary8u	(	const uint8_t *	a,
		size_t	aStride,
		const uint8_t *	b,
		size_t	bStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		uint8_t *	dst,
		size_t	dstStride,
		SimdOperationBinary8uType	type
	)

Performs an element-wise binary operation between two 8-bit images.

All images must have the same width, height and number of channels. The function processes width*channelCount unsigned 8-bit values in every row; every channel is handled independently. The exact operation is selected by type (average, bitwise AND/OR, maximum, minimum, saturated subtraction or saturated addition).

Note

This function has a C++ wrapper: Simd::OperationBinary8u(const View<A>& a, const View<A>& b, View<A>& dst, SimdOperationBinary8uType type).

Parameters

[in]	a	- a pointer to pixels data of the first input image.
[in]	aStride	- a row size of the first image.
[in]	b	- a pointer to pixels data of the second input image.
[in]	bStride	- a row size of the second image.
[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 the output image.
[in]	dstStride	- a row size of the output image.
[in]	type	- a type of operation (see SimdOperationBinary8uType).

SimdOperationBinary16i()

void SimdOperationBinary16i	(	const uint8_t *	a,
		size_t	aStride,
		const uint8_t *	b,
		size_t	bStride,
		size_t	width,
		size_t	height,
		uint8_t *	dst,
		size_t	dstStride,
		SimdOperationBinary16iType	type
	)

Performs an element-wise binary operation between two signed 16-bit images.

All images must have the same width, height and SimdPixelFormatInt16 pixel format. The function treats every row as an array of width signed 16-bit values and applies the non-saturated operation selected by type (addition or subtraction). Strides are specified in bytes and must be multiples of sizeof(int16_t).

Note

This function has a C++ wrapper: Simd::OperationBinary16i(const View<A>& a, const View<A>& b, View<A>& dst, SimdOperationBinary16iType type).

Parameters

[in]	a	- a pointer to pixels data of the first input image.
[in]	aStride	- a row size of the first image.
[in]	b	- a pointer to pixels data of the second input image.
[in]	bStride	- a row size of the second image.
[in]	width	- an image width.
[in]	height	- an image height.
[out]	dst	- a pointer to pixels data of the output image.
[in]	dstStride	- a row size of the output image.
[in]	type	- a type of operation (see SimdOperationBinary16iType).

OperationBinary8u()

void OperationBinary8u	(	const View< A > &	a,
		const View< A > &	b,
		View< A > &	dst,
		SimdOperationBinary8uType	type
	)

Performs an element-wise binary operation between two 8-bit images.

All images must have the same width, height and format (8-bit gray, 16-bit UV, 24-bit BGR/RGB or 32-bit BGRA/RGBA). Every channel is handled independently. The exact operation is selected by type (average, bitwise AND/OR, maximum, minimum, saturated subtraction or saturated addition).

Note

This function is a C++ wrapper for function SimdOperationBinary8u.

Parameters

[in]	a	- a first input image.
[in]	b	- a second input image.
[out]	dst	- an output image.
[in]	type	- a type of operation (see SimdOperationBinary8uType).

OperationBinary16i()

void OperationBinary16i	(	const View< A > &	a,
		const View< A > &	b,
		View< A > &	dst,
		SimdOperationBinary16iType	type
	)

Performs an element-wise binary operation between two signed 16-bit images.

All images must have the same width, height and Simd::View::Int16 pixel format. The function applies the non-saturated operation selected by type (addition or subtraction).

Note

This function is a C++ wrapper for function SimdOperationBinary16i.

Parameters

[in]	a	- a first input image.
[in]	b	- a second input image.
[out]	dst	- an output image.
[in]	type	- a type of operation (see SimdOperationBinary16iType).
