Member Function Documentation

computeSaliency()

bool cv::saliency::ObjectnessBING::computeSaliency ( InputArray image, OutputArray saliencyMap )

inline

Python:
	cv.saliency.ObjectnessBING.computeSaliency(	image[, saliencyMap]	) ->	retval, saliencyMap

Here is the call graph for this function:

computeSaliencyImpl()

bool cv::saliency::ObjectnessBING::computeSaliencyImpl ( InputArray image, OutputArray objectnessBoundingBox )

protectedvirtual

Performs all the operations and calls all internal functions necessary for the accomplishment of the Binarized normed gradients algorithm.

Parameters

image	input image. According to the needs of this specialized algorithm, the param image is a single Mat
objectnessBoundingBox	objectness Bounding Box vector. According to the result given by this specialized algorithm, the objectnessBoundingBox is a vector<Vec4i>. Each bounding box is represented by a Vec4i for (minX, minY, maxX, maxY).

Implements cv::saliency::Objectness.

Here is the call graph for this function:

create()

static Ptr< ObjectnessBING > cv::saliency::ObjectnessBING::create ( )

inlinestatic

Python:
	cv.saliency.ObjectnessBING.create(		) ->	retval
	cv.saliency.ObjectnessBING_create(		) ->	retval

getBase()

double cv::saliency::ObjectnessBING::getBase ( ) const

inline

Python:
	cv.saliency.ObjectnessBING.getBase(		) ->	retval

getNSS()

int cv::saliency::ObjectnessBING::getNSS ( ) const

inline

Python:
	cv.saliency.ObjectnessBING.getNSS(		) ->	retval

getobjectnessValues()

std::vector< float > cv::saliency::ObjectnessBING::getobjectnessValues

(

)

Python:
	cv.saliency.ObjectnessBING.getobjectnessValues(		) ->	retval

Return the list of the rectangles' objectness value,.

in the same order as the vector<Vec4i> objectnessBoundingBox returned by the algorithm (in computeSaliencyImpl function). The bigger value these scores are, it is more likely to be an object window.

getW()

int cv::saliency::ObjectnessBING::getW ( ) const

inline

Python:
	cv.saliency.ObjectnessBING.getW(		) ->	retval

read()

void cv::saliency::ObjectnessBING::read

(

)

Python:
	cv.saliency.ObjectnessBING.read(		) ->	None

setBase()

void cv::saliency::ObjectnessBING::setBase ( double val )

inline

Python:
	cv.saliency.ObjectnessBING.setBase(	val	) ->	None

setBBResDir()

void cv::saliency::ObjectnessBING::setBBResDir

(

const String &

resultsDir

)

Python:
	cv.saliency.ObjectnessBING.setBBResDir(	resultsDir	) ->	None

This is a utility function that allows to set an arbitrary path in which the algorithm will save the optional results.

(ie writing on file the total number and the list of rectangles returned by objectess, one for each row).

Parameters

resultsDir

results' folder path

setNSS()

void cv::saliency::ObjectnessBING::setNSS ( int val )

inline

Python:
	cv.saliency.ObjectnessBING.setNSS(	val	) ->	None

setTrainingPath()

void cv::saliency::ObjectnessBING::setTrainingPath

(

const String &

trainingPath

)

Python:
	cv.saliency.ObjectnessBING.setTrainingPath(	trainingPath	) ->	None

This is a utility function that allows to set the correct path from which the algorithm will load the trained model.

Parameters

trainingPath

trained model path

setW()

void cv::saliency::ObjectnessBING::setW ( int val )

inline

Python:
	cv.saliency.ObjectnessBING.setW(	val	) ->	None

write()

void cv::saliency::ObjectnessBING::write

(

)

const

Python:
	cv.saliency.ObjectnessBING.write(		) ->	None
