Detailed Description

Fuzzy transform (F-transform) of the 0th degree transform whole image to a vector of its components. These components are used in latter computation.

Function Documentation

void cv::ft::FT02D_components	(	InputArray	matrix,
		InputArray	kernel,
		OutputArray	components,
		InputArray	mask
	)

Computes components of the array using direct F0-transform.

Parameters

matrix	Input 1-channel array.
kernel	Kernel used for processing. Function createKernel can be used.
components	Output 32-bit array for the components.
mask	Mask can be used for unwanted area marking.

The function computes components using predefined kernel and mask.

Note

F-transform technique is described in paper [113].

int cv::ft::FT02D_iteration	(	const Mat &	image,
		const Mat &	kernel,
		Mat &	imageOutput,
		const Mat &	mask,
		Mat &	maskOutput,
		bool	firstStop = true
	)

Parameters

image	Input image.
kernel	Kernel used for processing. Function createKernel can be used.
imageOutput	Output 32-bit array.
mask	Mask used for unwanted area marking.
maskOutput	Mask after one iteration.
firstStop	If true function returns -1 when first problem appears. In case of false, the process is completed and summation of all problems returned.

This function computes iteration of F-transfrom and inverse F-transfotm and handle image and mask change. The function is used in inpaint function.

void cv::ft::FT02D_process	(	const Mat &	image,
		const Mat &	kernel,
