Detailed Description

This section describes conversion between OpenCV and Intel® IPP Asynchronous C/C++ library. Getting Started Guide help you to install the library, configure header and library build paths.

Function Documentation

copyHppToMat()

void cv::hpp::copyHppToMat	(	hppiMatrix *	src,
		Mat &	dst,
		hppAccel	accel,
		int	cn
	)

Convert hppiMatrix to Mat.

This function allocates and initializes new matrix (if needed) that has the same size and type as input matrix. Supports CV_8U, CV_16U, CV_16S, CV_32S, CV_32F, CV_64F.

Parameters

src	input hppiMatrix.
dst	output matrix.
accel	accelerator instance (see hpp::getHpp for the list of acceleration framework types).
cn	number of channels.

getHpp()

hppiMatrix* cv::hpp::getHpp	(	const Mat &	src,
		hppAccel	accel
	)

Create hppiMatrix from Mat.

This function allocates and initializes the hppiMatrix that has the same size and type as input matrix, returns the hppiMatrix*.

If you want to use zero-copy for GPU you should to have 4KB aligned matrix data. See details hppiCreateSharedMatrix.

Supports CV_8U, CV_16U, CV_16S, CV_32S, CV_32F, CV_64F.

Note

The hppiMatrix pointer to the image buffer in system memory refers to the src.data. Control the lifetime of the matrix and don't change its data, if there is no special need.

Parameters

src	input matrix.
accel	accelerator instance. Supports type: HPP_ACCEL_TYPE_CPU - accelerated by optimized CPU instructions. HPP_ACCEL_TYPE_GPU - accelerated by GPU programmable units or fixed-function accelerators. HPP_ACCEL_TYPE_ANY - any acceleration or no acceleration available.

getMat()

Mat cv::hpp::getMat	(	hppiMatrix *	src,
		hppAccel	accel,
		int	cn
	)

Create Mat from hppiMatrix.

This function allocates and initializes the Mat that has the same size and type as input matrix. Supports CV_8U, CV_16U, CV_16S, CV_32S, CV_32F, CV_64F.

Parameters

src	input hppiMatrix.
accel	accelerator instance (see hpp::getHpp for the list of acceleration framework types).
cn	number of channels.
