rle-stencils

Code to generate stencils for the rle level set processing libraries.

Basic Usage

To install the library, just do:

npm install rle-stencils

Then in your code you can import the stencil generators using:

var stencils = require('rle-stencils');

Example: Moore

Here is how to create a stencil for a Moore neighborhood with radius 2:

var moore_neighborhood = stencils.moore(2);

Example: von Neumann

And here is the same idea applied to a von Neumann neighborhood

var von_eumann_neighborhood = stencils.vonNeumann(1);

Example: Sphere

var ball_neighborhood = stencils.ball(5);

Example: L^p

More generally, you can create a stencil for any Lp ball, with p being some fixed power. For example, here is how to make an L^3 ball with radius 6:

var cubic_neighborhood = stencils.lp(3, 6);

In general, calls to lp(p, r) return the collection of all integer lattice points x satisfying the inequality:

Math.pow(Math.abs(x[0]), p) + Math.pow(Math.abs(x[1]), p) + Math.pow(Math.abs(x[2]), p) <= Math.pow(r, p)
