Class BinaryInterpolation2D

java.lang.Object

ini.trakem2.imaging.BinaryInterpolation2D

All Implemented Interfaces:

Algorithm, OutputAlgorithm<BitType>

public class BinaryInterpolation2D
extends Object
implements OutputAlgorithm<BitType>

Given two binary images of the same dimensions, generate an interpolated image that sits somewhere in between, as specified by the weight. For each binary image, the edges are found and then each pixel is assigned a distance to the nearest edge. Inside, distance values are positive; outside, negative. Then both processed images are compared, and wherever the weighted sum is larger than zero, the result image gets a pixel set to true (or white, meaning inside). A weight of zero means that the first image is not present at all in the interpolated image; a weight of one means that the first image is present exclusively. The code was originally created by Johannes Schindelin in the VIB's vib.BinaryInterpolator class, for ij.ImagePlus.

Method Summary

Modifier and Type	Method and Description
boolean	checkInput()
String	getErrorMessage()
Image<BitType>	getResult()
boolean	process()
Image<BitType>	process(float weight) The first time, it will prepare the distance transform images, which are computed only once.
void	setWeight(float weight) After changing the weight, it's totally valid to call process() again, and then getResult().
