Detailed Description

Function Documentation

◆ copyMakeBorder()

void cv::cuda::copyMakeBorder ( InputArray  src,
OutputArray  dst,
int  top,
int  bottom,
int  left,
int  right,
int  borderType,
Scalar  value = Scalar(),
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

Forms a border around an image.

Parameters
srcSource image. CV_8UC1 , CV_8UC4 , CV_32SC1 , and CV_32FC1 types are supported.
dstDestination image with the same type as src. The size is Size(src.cols+left+right, src.rows+top+bottom) .
topNumber of top pixels
bottomNumber of bottom pixels
leftNumber of left pixels
rightNumber of pixels in each direction from the source image rectangle to extrapolate. For example: top=1, bottom=1, left=1, right=1 mean that 1 pixel-wide border needs to be built.
borderTypeBorder type. See borderInterpolate for details. BORDER_REFLECT101 , BORDER_REPLICATE , BORDER_CONSTANT , BORDER_REFLECT and BORDER_WRAP are supported for now.
valueBorder value.
streamStream for the asynchronous version.

◆ createLookUpTable()

Ptr<LookUpTable> cv::cuda::createLookUpTable ( InputArray  lut)

#include <opencv2/cudaarithm.hpp>

Creates implementation for cuda::LookUpTable .

Parameters
lutLook-up table of 256 elements. It is a continuous CV_8U matrix.

◆ flip()

void cv::cuda::flip ( InputArray  src,
OutputArray  dst,
int  flipCode,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

Flips a 2D matrix around vertical, horizontal, or both axes.

Parameters
srcSource matrix. Supports 1, 3 and 4 channels images with CV_8U, CV_16U, CV_32S or CV_32F depth.
dstDestination matrix.
flipCodeFlip mode for the source:
  • 0 Flips around x-axis.
  • > 0 Flips around y-axis.
  • < 0 Flips around both axes.
streamStream for the asynchronous version.

◆ merge() [1/2]

void cv::cuda::merge ( const GpuMat src,
size_t  n,
OutputArray  dst,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

Makes a multi-channel matrix out of several single-channel matrices.

Parameters
srcArray/vector of source matrices.
nNumber of source matrices.
dstDestination matrix.
streamStream for the asynchronous version.

◆ merge() [2/2]

void cv::cuda::merge ( const std::vector< GpuMat > &  src,
OutputArray  dst,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ split() [1/2]

void cv::cuda::split ( InputArray  src,
GpuMat dst,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

Copies each plane of a multi-channel matrix into an array.

Parameters
srcSource matrix.
dstDestination array/vector of single-channel matrices.
streamStream for the asynchronous version.

◆ split() [2/2]

void cv::cuda::split ( InputArray  src,
std::vector< GpuMat > &  dst,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ transpose()

void cv::cuda::transpose ( InputArray  src1,
OutputArray  dst,
Stream stream = Stream::Null() 
)

#include <opencv2/cudaarithm.hpp>

Transposes a matrix.

Parameters
src1Source matrix. 1-, 4-, 8-byte element sizes are supported for now.
dstDestination matrix.
streamStream for the asynchronous version.
