TR2ofimage

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - VM/Voxels
Introduced first in SolidGeometry 2.1, Creation date: 2015-01-20, Last change: 2025-09-14

returns a Delaunay triangulation for a grayscale image

Description

Type = 0 => triangulation contains all pixels and pixel facets
Type = 1 => triangulation contains only triangulated boundary facets

WARNING: This function contains a real Matlab coding bug: If the two lines of function TR2reduce are directly inserted in the code, an error occurs by the isInterior procedure that is not explainable.

Example Illustration

missing image of TR2ofimage(I,t)

Syntax

TR2=TR2ofimage(I,[t])

Input Parameter

I: Image nxm
t: type of triangulation (default is 1)

Output Parameter

TR2: delaunay triangulation

Examples

Analyze dicom images:
subplot (1,2,1); TR2ofimage (I1>1400,0);
subplot (1,2,2); TR2ofimage (I1>1400,1);
