Function Documentation

void cv::ft::createKernel ( cv::InputArray  A,
cv::InputArray  B,
cv::OutputArray  kernel,
const int  chn = 1 
)

Creates kernel from basic functions.

Parameters
ABasic function used in axis x.
BBasic function used in axis y.
kernelFinal 32-b kernel derived from A and B.
chnNumber of kernel channels.

The function creates kernel usable for latter fuzzy image processing.

void cv::ft::createKernel ( int  function,
int  radius,
cv::OutputArray  kernel,
const int  chn = 1 
)

Creates kernel from general functions.

Parameters
functionFunction type could be one of the following:
  • LINEAR Linear basic function.
radiusRadius of the basic function.
kernelFinal 32-b kernel.
chnNumber of kernel channels.

The function creates kernel from predefined functions.

void cv::ft::filter ( const cv::Mat image,
const cv::Mat kernel,
cv::Mat output 
)

Image filtering.

Parameters
imageInput image.
kernelFinal 32-b kernel.
outputOutput 32-bit image.

Filtering of the input image by means of F-transform.

void cv::ft::inpaint ( const cv::Mat image,
const cv::Mat mask,
cv::Mat output,
int  radius = 2,
int  function = ft::LINEAR,
int  algorithm = ft::ONE_STEP 
)

Image inpainting.

Parameters
imageInput image.
maskMask used for unwanted area marking.
outputOutput 32-bit image.
radiusRadius of the basic function.
functionFunction type could be one of the following:
  • LINEAR Linear basic function.
algorithmAlgorithm could be one of the following:
  • ONE_STEP One step algorithm.
  • MULTI_STEP Algorithm automaticaly increasing radius of the basic function.
  • ITERATIVE Iterative algorithm running in more steps using partial computations.

This function provides inpainting technique based on the fuzzy mathematic.

Note
The algorithms are described in paper [119].
