Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`afterCycle()`	Called by the ThinningOp after each cycle, and thus exactly getIterationsPerCycle()-times per iteration.
`ThinningStrategy`	`copy()`	Returns a separate copy of this strategy.
`int`	`getIterationsPerCycle()`	Returns the minimum number of iterations necessary for the algorithm to run.
`boolean`	`removePixel(long[] position, RandomAccessible<BitType> accessible, int iteration)`	This method should determine whether to keep a foreground pixel or not.

- Method Detail
  - removePixel
```
boolean removePixel(long[] position,
                    RandomAccessible<BitType> accessible,
                    int iteration)
```
    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
```
int getIterationsPerCycle()
```
    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.
    
    Returns:
    
    The number of iterations per cycle.
  - afterCycle
```
void afterCycle()
```
    Called by the ThinningOp after each cycle, and thus exactly getIterationsPerCycle()-times per iteration. Used for performing different calculations in each step of the cycle.
  - copy
```
ThinningStrategy copy()
```
    Returns a separate copy of this strategy.
    
    Returns:
    
    A new instance of this strategy with the same values.
