I have this image and when I'm trying to generate it into the 3D surface it appears some noises in the graph.
Can anyone help me with some noise removal suggestion?

How about applying median filter?
The following is an example:
% Read the image and convert it to grya-scale
I = imread('gray.png');
Igray = rgb2gray(I);
% Apply median filter to the image
Igray2 = medfilt2(Igray,[7 7]);
% Show the result
figure
imshowpair(Igray,Igray2,'montage')

That's not enough. That gives you the field of view in pixels, but not in microns or mm. By the way, a 1154 x 1152 image is 1.3 megapixels, far from 48 megapixels - not even close.

I search from some paper about fringe pattern they using fast fourier transform and get the value of x,y,z axis in mm
