public AbstractDistanceMetric()
```
- Method Detail
  - create
```
public double[][] create(int masksize)
```
    Creates a distance metric mask with given masksize
    
    Parameters:
    
    masksize - masksize of the distance metric must be odd and >= 3 (because a distance metric of 1 is always 0)
    
    Returns:
    
    distance metric
  - calculateMaskValue
```
protected abstract double calculateMaskValue(int x,
                                             int y)
```
    Method which calculates the mask value at the given position
    
    Parameters:
    
    x - x position
    
    y - y position
    
    Returns:
    
    mask value for the given position
