in what form the "image is given" ? (normally as full matrix with
numerical values corresponding to (height, colors, temperature.. )
and for a complete square grid there is no problem to write down the
triangular grid. if you have scattered data in the plane, then you must use
delaunay triangulation and there is indeed free software for this
for example inhttp://www.netlib.org/toms

Thank you for the response. The image is in B&W BMP format with some
sharp edges and some grey edges. I am looking for a software that can
generate a 2D triangular mesh from this image.

One possible solution would be to convert the image to a unevenly
distributed point map and then use the delaunay triangulation. Again,
I am looking for a code to get the uneven point map.- Hide quoted text -

On a second thought, I am looking for a software for image
segmentation and meshing.
