delaunay

Arguments:

_output_type={ 0:Image | 1:Coordinates/triangles }

Description:

Generate discrete 2D Delaunay triangulation of non-zero pixels in selected images.

Input images must be scalar.
Each pixel of the output image is a triplet (a,b,c) meaning the pixel belongs to
the Delaunay triangle ABC where a,b,c are the labels of the pixels A,B,C.

Examples of use:

• Example #1

400,400 rand 32,255 100%,100% noise. 0.4,2 eq. 1 mul +delaunay

Command: 400,400 rand 32,255 100%,100% noise. 0.4,2 eq. 1 mul +delaunay

Command: 400,400 rand 32,255 100%,100% noise. 0.4,2 eq. 1 mul +delaunay
