Detailed Description

A DIRECTED recursive method for visiting pixels of a segment in an image.

A helper class applied by FloodFillOp and SegmentAreaOp.

Template Parameters

S	- storage type of the source image data (int by default, but should be floating-type, if src is).
D	- storage type of the destination image data
C	- configuration type,

Member Function Documentation

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.

inlinevirtual

Application dependent. Assumes checked coordinates.

Parameters

pos	- new position (validated coordinates)
dir	- direction of entry (from outside to inside [potential new segment])

Returns: - true, if this pixel belongs to a new segment, and false if probing can continue

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.
