Constructor & Destructor Documentation

◆ CIntensity()

DirectGraphicalModels::fex::CIntensity::CIntensity ( const Mat & img )

inline

Constructor.

Parameters

img	Input image of type CV_8UC3.

Definition at line 21 of file Intensity.h.

◆ ~CIntensity()

virtual DirectGraphicalModels::fex::CIntensity::~CIntensity ( void )

inlinevirtual

Definition at line 22 of file Intensity.h.

Member Function Documentation

◆ get() [1/2]

virtual Mat DirectGraphicalModels::fex::CIntensity::get ( void ) const

inlinevirtual

Extracts and returns the required feature.

Returns: The feature image.

Implements DirectGraphicalModels::fex::ILocalFeatureExtractor.

Definition at line 24 of file Intensity.h.

Here is the caller graph for this function:

◆ get() [2/2]

Mat DirectGraphicalModels::fex::CIntensity::get	(	const Mat &	img,
		cv::Scalar	weight = `CV_RGB(0.333, 0.333, 0.333)`
	)

static

Extracts the intesity feature.

This function calculates the intesity of the input image as follows:

\[ intensity=weight_0\cdot img.RED+weight_1\cdot img.GREEN+weight_2\cdot img.BLUE \]

Parameters

img	Input image of type CV_8UC3.
weight	The weight coefficients, which determine the contribution of each color channel to the resulting intensity.

Returns: The intesity feature image of type CV_8UC1.
