template<class StorageType >

double BIAS::IntegralImage< StorageType >::GetAreaAvg ( const int &  xA, const int &  yA, const int &  xB, const int &  yB  )

inline

Evaluate the integral image.

Returns the average value in the rectangle with the upper left corner (xA,yA) and lower right corner (xB,yB).

Parameters

xA	left border
yA	upper border
xB	right border
yB	lower border

Definition at line 77 of file IntegralImage.hh.

template<class StorageType >

StorageType BIAS::IntegralImage< StorageType >::GetAreaAvgRd ( const int &  xA, const int &  yA, const int &  xB, const int &  yB  )

inline

Evaluate the integral image.

Returns the rounded average value in the rectangle with the upper left corner (xA,yA) and lower right corner (xB,yB) cast to StorageType.

Parameters

xA	left border
yA	upper border
xB	right border
yB	lower border

Definition at line 94 of file IntegralImage.hh.

template<class StorageType >

double BIAS::IntegralImage< StorageType >::GetAreaSum ( const int &  xA, const int &  yA, const int &  xB, const int &  yB  )

inline

Evaluate the integral image.

Returns the sum of values in the rectangle with the upper left corner (xA,yA) and lower right corner (xB,yB).

Parameters

xA	left border
yA	upper border
xB	right border
yB	lower border

Definition at line 61 of file IntegralImage.hh.

template<class StorageType >

double IntegralImage::GetDOM	(	int	x,
		int	y,
		int	halfLevelSize
	)

Calculate the difference of means (DOM) at a given position with a given scale (halfWinSize).

This can be used as a fast alternative to the difference of gaussian (DOG) based scale space.

Parameters

x	x position in the DOM space
y	y position in the DOM space
halfWinSize	The half windows size of the inner area (which is subtracked by an area with 2*halfWinSize)

Definition at line 70 of file IntegralImage.cpp.

template<class StorageType >

double* BIAS::IntegralImage< StorageType >::GetIntImageData

(

)

Get the raw data pointer to the integral image.
