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 
)
inline

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
srcinput hppiMatrix.
dstoutput matrix.
accelaccelerator instance (see hpp::getHpp for the list of acceleration framework types).
cnnumber of channels.

§ getHpp()

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

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
srcinput matrix.
accelaccelerator 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 
)
inline

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
srcinput hppiMatrix.
accelaccelerator instance (see hpp::getHpp for the list of acceleration framework types).
cnnumber of channels.

§ toCvType()

int cv::hpp::toCvType ( const int  hppType)
inline

convert hppDataType to OpenCV data type

§ toHppType()

int cv::hpp::toHppType ( const int  cvType)
inline

convert OpenCV data type to hppDataType
