Method Detail

run

public IResult run(IWorkPackage wp)

Description copied from interface: IOperator

This method contains the entire logic (algorithm) of the operator. An IOperator does not declare any class members, since the execution of this code must be thread-safe.

Specified by:

run in interface IOperator

Specified by:

run in class AbstractOperator

Parameters:

wp - the parameters and sources

Returns:

a IResult containing all processed data

getName

public String getName()

Description copied from interface: IOperator

Gets the unique name of the IOperator by returning the "GlobalName" element from the resources[][] of the associated IOperatorDescriptor.

Specified by:

getName in interface IOperator

Specified by:

getName in class AbstractOperator

Returns:

the unique name of the operator

getType

public OperatorType getType()

Description copied from interface: IOperator

Gets the type of the operator listed in an enumeration.

Specified by:

getType in interface IOperator

Specified by:

getType in class AbstractOperator

Returns:

the OperatorType

calcRegGrow

private void calcRegGrow(Point seedPoint,
                         int seedcount)

Calculates the RegGrow-Algorithm for one seedPoint

Parameters:

seedPoint -

checkPoint

private void checkPoint(Point p,
                        int seedcount)

Checks whether the point should be pushed on the stack or not

Parameters:

p -

setPixelTrue

private void setPixelTrue(Point p,
                          int seedcount)

Set the corresponding point in the controllArray to 1

Parameters:

p -

isInRange

private boolean isInRange(double greyValue)

Checks if the grey value is bigger than min grey value and smaller than max grey value

Parameters:

greyValue -

Returns:

true if the grey value is in range

isPointWithinBounds

private boolean isPointWithinBounds(Point p)

Check if the point is within bounds or not

Parameters:

p -

Returns:

true if the point is within bounds

markRegions

private void markRegions(int seedcount)

Set all pixel black which are not part of any region
