CvGabor::CvGabor	(	int	iMu,
		int	iNu
	)

Construct a gabor

Parameters: iMu The orientation iMu*PI/8, iNu The scale,

Returns: None,

Create a gabor with a orientation iMu*PI/8, and with a scale iNu. The sigma (Sigma) and the spatial frequence (F) are set to 2*PI and sqrt(2) defaultly. It calls Init() to generate parameters and kernels.

long CvGabor::get_mask_width ( )

Reads the width of Mask

Parameters: None

Returns: Pointer to long type width of mask.

Definition at line 391 of file cvgabor.cpp.

CvMat * CvGabor::get_matrix ( int Type )

Get a matrix by the type of kernel

Parameters: Type The type of kernel, e.g. REAL, IMAG, MAG, PHASE

Returns: Pointer to matrix structure, or NULL on failure.

Return the gabor kernel.

Definition at line 486 of file cvgabor.cpp.

void CvGabor::Init	(	int	iMu,
		int	iNu,
		double	dSigma,
		double	dF
	)

Initilize the.gabor

Parameters: iMu The orientations which is iMu*PI.8 iNu The scale can be from -5 to infinit dSigma The Sigma value of gabor, Normally set to 2*PI dF The spatial frequence , normally is sqrt(2)

Returns:

Initilize the.gabor with the orientation iMu, the scale iNu, the sigma dSigma, the frequency dF, it will call the function creat_kernel(); So a gabor is created.

Definition at line 411 of file cvgabor.cpp.

void CvGabor::Init	(	double	dPhi,
		int	iNu,
		double	dSigma,
		double	dF
	)

Initilize the.gabor

Parameters: dPhi The orientations iNu The scale can be from -5 to infinit dSigma The Sigma value of gabor, Normally set to 2*PI dF The spatial frequence , normally is sqrt(2)

Returns: None

Initilize the.gabor with the orientation dPhi, the scale iNu, the sigma dSigma, the frequency dF, it will call the function creat_kernel(); So a gabor is created.filename The name of the image file file_format The format of the file, e.g. GAN_PNG_FORMAT image The image structure to be written to the file octrlstr Format-dependent control structure

Definition at line 452 of file cvgabor.cpp.

bool CvGabor::IsInit ( )

Determine the gabor is initilised or not

Parameters: None

Returns: a boolean value, TRUE is initilised or FALSE is non-initilised.

Determine whether the gabor has been initlized - variables F, K, Kmax, Phi, Sigma are filled.

Definition at line 180 of file cvgabor.cpp.

bool CvGabor::IsKernelCreate ( )

Determine the gabor kernel is created or not

Parameters: None

Returns: a boolean value, TRUE is created or FALSE is non-created.

Determine whether a gabor kernel is created.

Definition at line 374 of file cvgabor.cpp.

long CvGabor::mask_width ( )

Give out the width of the mask

Parameters: None

Returns: The long type show the width.

Return the width of mask (should be NxN) by the value of Sigma and iNu.

Definition at line 198 of file cvgabor.cpp.

void CvGabor::output_file	(	const char *	filename,
		int	Type
	)
