Class Threshold_Image

java.lang.Object

mtb_segmentation.Threshold_Image

All Implemented Interfaces:

ij.gui.DialogListener, ij.plugin.filter.PlugInFilter

public class Threshold_Image
extends Object
implements ij.plugin.filter.PlugInFilter, ij.gui.DialogListener

Plugin for thresholding plain images, stacks and hyperstacks. The output image is of the datatype of the input image. The output might contain values different from 0 depending on the image's datatype:
Byte images: Output values are 0 for black and 255 for white, if the 'original pixel values' option was not chosen.
Short images: Output values are 0 for black and the maximum gray value of the input image for white.
Floating point images: Output values are the minimum gray value of the input image for black and the maximum gray value for white.
