Detailed Description

class that implements a simple flood fill Based on recursive implementation described in http://en.wikipedia.org/wiki/Flood_fill

Member Function Documentation

common::RectangularROI< int > stira::imageanalysis::FloodFill::GetBoundingBox

(

)

Gets the bounding box of the region that was flooded if the region was empty, the point (0,0) is returned.

Warning

call is only valid after Run was called!!!

Returns

point that is center of gravity of the pixels that were flooded during the Run

common::Point< double > stira::imageanalysis::FloodFill::GetCenterOfGravity

(

)

Gets the center of gravity of the region that was flooded if the region was empty, the point (0,0) is returned.

Warning

call is only valid after Run was called!!!

Returns

point that is center of gravity of the pixels that were flooded during the Run

std::vector< Point< int > > stira::imageanalysis::FloodFill::GetFloodedPixels

(

)

Gets a vector with the pixels that were flooded during the Run.

Warning

call is only valid after Run was called!!!

Returns

vector with the pixels that were flooded during the Run

ArrayGrid< int > * stira::imageanalysis::FloodFill::PrepareValues ( ArrayGrid< double > *  pGrid, int  lowerBound, int  upperBound, int  targetValue  )

static

allows to prepare a help grid to deal with filling between two thresholds instead of filling a single value in a grid

Parameters

pGrid	input grid
lowerBound	lower bound value for filling
upperBound	upper bound value for filling
targetValue	value that all values in the range between lowerBound and upperBound are replaced with

Returns

a new grid in which the range between lowerBound and upperBound is replaced by a single value

Warning

the return grid becomes the responsability of the caller to delete.

int stira::imageanalysis::FloodFill::Run	(	ArrayGrid< int > *	pGrid,
		int	nodeX,
		int	nodeY,
		int	targetValue,
		int	replacementValue,
		bool	fill8Connected = true
	)

Run method of the fill.

Parameters

pGrid	grid to be filled
nodeX	x coordinate of starting seed
nodeY	y coordinate of starting seed
targetValue	value to be replaced
replacementValue	value to replace targetValue by

Returns

the number of pixels filled by this flooding
