Detailed Description

template<class C, class R = RadarWindowCore>
class rack::SlidingRadarWindowBase< C, R >

A two-dimensional image processing window that handles the special ODIM codes and scales the result. Template parameter for drain::SlidingWindowOpT.

Template Parameters

C	- configuration structure
R	- window core (input and output members)

drain::image::WindowCore supports single-src, single-dst (with respective weights).

Member Function Documentation

◆ initialize()

template<class C , class R = RadarWindowCore>

virtual void initialize ( )

inlineoverrideprotectedvirtual

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 >.

Reimplemented in DopplerWindow, and DopplerInversionWindow.

◆ reset()

template<class C , class R = RadarWindowCore>

virtual bool reset ( )

inlineprotectedvirtual

Returns false, if traversal should be ended.

Reimplemented from SlidingWindow< C, R >.

◆ setImageLimits()

template<class C , class R = RadarWindowCore>

void setImageLimits ( ) const

inlineprotectedvirtual

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 >.

◆ setRangeNorm()

template<class C , class R = RadarWindowCore>

void setRangeNorm ( )

inlineprotected

To compensate polar geometry, set applicable range for pixel area scaling.

Distance [bins] at which a bin is (nearly) square, ie. beam-perpendicular and beam-directional steps are equal.

Distance [bins] at which a single azimuthal step is equal to conf.frame.height steps at rangeNorm.

◆ setSrcFrame()

template<class C , class R = RadarWindowCore>

void setSrcFrame ( const drain::image::ImageFrame & src )

inlinevirtual

Sets input image and retrieves ODIM metadata from image Properties.

Reimplemented from WindowCoreBase.
