Detailed Description

A helper class applied by FloodFillOp and SegmentAreaOp.

Template Parameters

T	- type of the source image (int by default, but should be floating-type, if src is).
D	- type of the destination image, the image to be filled.

Member Function Documentation

virtual void clear ( )

inlineprotectedvirtual

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.

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.
