Member Function Documentation

◆ addPixel()

template<class R = OpticalFlowCore2>

virtual void addPixel ( Point2D< int > & p )

inlinevirtual

Adds a pixel to window statistics. Unvalidated location.

Updates class-specific window statistics by adding a pixel value - typically at the leading edge of the window.

Parameters

p	- location at which contribution should be removed

The argument p is not validated in advance but it should be checked within the implementation using coordinateHandler.validate(p), for example.

Implements SlidingWindow< C, R >.

Reimplemented in SlidingOpticalFlowWeighted2.

◆ clear()

template<class R = OpticalFlowCore2>

virtual void clear ( )

inlineprotectedvirtual

Clears the applied statistics. Redefined in derived classes.

Reimplemented from SlidingWindow< C, R >.

◆ initialize()

template<class R >

void initialize ( )

virtual

Sets class-specific initial values. Does not change general window state (e.g. location). Should not accumulate any statistics.

See also: fill(); clear()

Implements SlidingWindow< C, R >.

◆ removePixel()

template<class R = OpticalFlowCore2>

virtual void removePixel ( Point2D< int > & p )

inlinevirtual

Removes a pixel from window statistics. Unvalidated location.

     Updates class-specific window statistics by removing a pixel value  - typically at the trailing edge of the window.

     \param p - location at which contribution should be removed
    const int h = (conf.height>0.0) ? conf.height : conf.width;

GaussianStripeVert window2(h, 0.5*conf.radius*static_cast{double}(h)); GaussianStripe2<false> window2(h, 0.5*conf.radius*static_cast{double}(h));

 The argument p is \em not validated in advance but
 it should be checked within the implementation using coordinateHandler.validate(p), for example.

Implements SlidingWindow< C, R >.

Reimplemented in SlidingOpticalFlowWeighted2.

◆ setImageLimits()

template<class R = OpticalFlowCore2>

virtual void setImageLimits ( ) const

inlinevirtual

Sets internal limits corresponding to image geometries. Typically using coordHandler.

Studies source image(s) and sets srcWidth, srcHeight and coordHandler. Consider already implemented methods like WindowCore::adjustCoordHandler()

Implements Window< C, R >.

◆ write()

template<class R = OpticalFlowCore2>

virtual void write ( )

inlinevirtual

Returns the mean squared error of predicted.

Implements SlidingWindow< C, R >.
