public GuoHallThinningStrategy()
```
  - GuoHallThinningStrategy
```
public GuoHallThinningStrategy(boolean foreground)
```
    Create a new Guo-Hall thinning strategy. The passed boolean will represent the foreground-value of the image.
    
    Parameters:
    
    foreground - Value determining the boolean value of foreground pixels.

  - removePixel
```
public boolean removePixel(long[] position,
                           RandomAccessible<BitType> accessible,
                           int iteration)
```
    Description copied from interface: ThinningStrategy
    
    This method should determine whether to keep a foreground pixel or not.
    
    Parameters:
    
    position - Long Array containing the current position in the image.
    
    accessible - The image to thin.
    
    iteration - The iteration number.
    
    Returns:
    
    True if pixel can be switched to background, false otherwise.
  - getIterationsPerCycle
```
public int getIterationsPerCycle()
```
    Description copied from interface: ThinningStrategy
    
    Returns the minimum number of iterations necessary for the algorithm to run. This delays termination of the thinning algorithm until the end of the current cycle. If, for example, no changes occur during the second iteration of a 4-iteration-cycle, iterations 3 and 4 still take place.
    
    Specified by:
    
    getIterationsPerCycle in interface ThinningStrategy
    
    Overrides:
    
    getIterationsPerCycle in class Abstract3x3NeighbourhoodThinning
    
    Returns:
    
    The number of iterations per cycle.
  - copy
```
public ThinningStrategy copy()
```
    Description copied from interface: ThinningStrategy
    
    Returns a seperate copy of this strategy.
    
    Returns:
    
    A new instance of this strategy with the same values.
