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< int, int, SegmentProberConf< int, int > >.

isValidSegment()

virtual bool isValidSegment ( int  i, int  j  ) const

inlinevirtual

Application dependent, to be redefined. Assumes checked coordinates.

Determines if the current position is within a segment. The criterion of "segment" depends on the application.

Note: does not check coordinates, assumes them to be checked by the calling scope.

Implements SegmentProber< int, int, SegmentProberConf< int, int > >.

isVisited()

virtual bool isVisited ( int  i, int  j  ) const

inlinevirtual

Experimental.

Reimplemented from SegmentProber< int, int, SegmentProberConf< int, int > >.

update()

virtual void update ( int  i, int  j  )

inlinevirtual

Application dependent operation performed in each segment location (i,j).

Reimplemented from SegmentProber< int, int, SegmentProberConf< int, int > >.

Reimplemented in PolarSegmentProber.

visit()

virtual void visit ( int  i, int  j  )

inlinevirtual

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< int, int, SegmentProberConf< int, int > >.
