Member Function Documentation

clear()

virtual void clear ( )

inlinevirtual

Called before processing each segment. Compare with init(), which is called once for each image.

Application dependent initialisation for statistics updated with update(int i, int j) function.

Reimplemented from SegmentProber< double, double, drain::image::SegmentProberConf< double, double > >.

init()

virtual void init ( )

inlinevirtual

Update srcOdim.

Reimplemented from SegmentProber< double, double, drain::image::SegmentProberConf< double, double > >.

isValidMove()

virtual bool isValidMove ( int  i0, int  j0, int  i, int  j  ) const

inlineprotectedvirtual

Application dependent.

Returns

true, if the jump is small enough

TODO: add diff check to both normal and wrapped step.

Reimplemented from SegmentProber< double, double, drain::image::SegmentProberConf< double, double > >.

isValidSegment()

virtual bool isValidSegment ( int  i, int  j  ) const

inlineprotectedvirtual

Returns true, if value in location (i,j) is not nodata nor undetect .

Implements SegmentProber< double, double, drain::image::SegmentProberConf< double, double > >.

visit()

virtual void visit ( int  i, int  j  )

inlineprotectedvirtual

Visiting a single pixel when not coming from any direction.

Visiting means

• updating the status of this prober, for example by updating statistics like segment size
• marking the pixel visited in dst image

Parameters

i0	- current i coordinate (always valid)
j0	- current j coordinate (always valid)

Mark visited

Reimplemented from SegmentProber< double, double, drain::image::SegmentProberConf< double, double > >.
