Constructor Detail

ZhangSuenThinningStrategy

public ZhangSuenThinningStrategy()

ZhangSuenThinningStrategy

public ZhangSuenThinningStrategy(boolean foreground)

Create a new Zhang-Suen thinning strategy. The passed boolean will represent the foreground-value of the image.

Parameters:

foreground - Value determining the boolean value of foreground pixels.

Method Detail

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.

public ThinningStrategy copy()

Description copied from interface: ThinningStrategy

Returns a separate copy of this strategy.
