ImageJ plugin for the computing Two-Point Correlation.
In a two-component system, the two-point correlation represents the probability that two random points separated by a distance R will both lie in the same component.
The plugin scans a user-chosen number of random point pairs in regular increments of separation between 0 and Rmax.
Rmax is half the smallest image dimension
The plugin requires an image that has been segmented into zero and non-zero components.
The image can be a 2D image, a stack of 2D images, or a 3D image.
Anisotropic pixels and voxels are supported.
The pixel units and lengths must remain constant in the image (no irregular spacings).
Geometric distances are converted to pixel coordinates by rounding to the nearest integer.
Two Point Correlation Dialog
Value to process - Select the zero or non-zero component to measure
Calculate - Options are Current Slice, All Slices 2D, All Slices 3D. All Slices 2D is useful for stacks that vary in a non-spatial dimension such as time or concentration etc. This option reports its results in a stack plot and a table of profile values for each slice.
Number of Samples - Select the number of two=point pairs at each distance. More samples decreases noise.
Show Progress - Displays a progress bar while executing.
