ImageJ plugin for the computing Lineal Path Distribution.

In a two-component system, the Lineal Path represents the probability that a random line of length L will lie completely within the same component.

• The plugin scans a user-chosen number of lines of length L in regular increments between 0 and L_max.
• L_max 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.
• The pixel coordinates along the line are determined by Bresenham's line drawing algorithm

• 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.
