Member Function Documentation

compute()

virtual void cv::face::BIF::compute ( InputArray  image, OutputArray  features  ) const

pure virtual

Python:
	features	=	cv.face_BIF.compute(	image[, features]	)

Computes features sby input image.

Parameters

image	Input image (CV_32FC1).
features	Feature vector (CV_32FC1).

create()

static Ptr<BIF> cv::face::BIF::create ( int  num_bands = 8, int  num_rotations = 12  )

static

Python:
	retval	=	cv.face.BIF_create(	[, num_bands[, num_rotations]]	)

Parameters

num_bands	The number of filter bands (<=8) used for computing BIF.
num_rotations	The number of image rotations for computing BIF.

Returns

Object for computing BIF.

getNumBands()

virtual int cv::face::BIF::getNumBands ( ) const

pure virtual

Python:
	retval	=	cv.face_BIF.getNumBands(		)

Returns
