Hi all,
I need some help extracting the cross-mesh periodic pattern of the Proj2.jpg image that I've attached, and I'm very rusty with Matlab coding.
I have a good idea of how to perform this. I would assume you would take a fft of the image, keep the spikes, and perhaps taking the log of the magnitude to get the crossed mesh pattern out of it.
But I really am lost about how to perform this coding-wise in Matlab. Could anyone on here show me an example? Thank You!

By the way, I have attached the output image I am trying to get out of the original Proj2.jpg image.

Why did you start this question all over again when I already gave you the answer in http://www.mathworks.com/matlabcentral/answers/90218#comment_174284, which is your duplicate question? WHy would you want answers split among multiple discussions?
