Class ClosingFilter

java.lang.Object
  net.sourceforge.javaocr.plugin.morphology.ClosingFilter

All Implemented Interfaces:

ImageFilter

public class ClosingFilter
extends Object
implements ImageFilter

Apply closing by structuring element to binarized source image. TODO Works for binarized images only, could be extended to grayscale. The closing of an image A by a structuring element B is obtained by the dilation of A by B, followed by erosion of the resulting structure by B. http://en.wikipedia.org/wiki/Closing_(morphology)
