Creating a 2D mesh of a real image

Hello,

I want to create a 4*4, 2 dimentional mesh of an image of a composite material (containing an inclusion).

I have tried to collect data from the image using the function size, however i do not know how to procede for the mesh.

Thank you.

Have a read here and here. It will greatly improve your chances of getting an answer.

Both your input data and your desired output is unclear to me.

Hello, sorry i haven't asked my question properly.

Here is an example of the output that i want to have:

but with the circle also meshed ( so i need to recognize the contour of the circle?)

Here is my attempt of the code:

Your question is still not clear to me, and I can't run your code because you decided to post it as an image.

rows=251;
columns=257;

[R, C] = meshgrid(1:10:rows, 1:10:columns);
r=size(R)
c=size(C)
Z=zeros(r(1),c(2));

T = delaunay(R,C);
trimesh(T,R,C,Z)
view(0,300)

I have been able to visualize a mesh of a rectangle, as shown in this figure:

I want now to mesh a circle inside of it(wich will represent the inclusion).

Your help will be appreciated.
