how to differentiate tree and grass in an infrared image with matlab

Hello. I'm doing assignment project using infrared images. I would like to segment the images into certain regions to differentiate whether it is tree or grass.

You forgot to attach an image. Assuming that they have different reflectances in the IR band, you might be able to use thresholding. We'll know more after you attach your image. By the way, what band are you using? SWIR, MWIR, or thermal?

here is the image which i want to process

In that spectral band, the trees and the grass have the same reflectance. It will be very inaccurate if you just say that a certain reflectance (gray level) is grass and another is trees. Even if you use stdfilt() to do a texture filter (grass looks smoother), I think you will still have a lot of false positives. I'd choose another project if I were you.
