Here is a sample MATLAB code for Fourier Transform Profilometry:
```matlab
% Load the fringe images
I1 = imread('image1.jpg');
I2 = imread('image2.jpg');
I3 = imread('image3.jpg');
I4 = imread('image4.jpg');
% Convert the images to grayscale
I1 = rgb2gray(I1);
I2 = rgb2gray(I2);
I3 = rgb2gray(I3);
I4 = rgb2gray(I4);
% Calculate the wrapped phase map for each image
phase_map1 = atan2(double(I4 - I2), double(I3 - I1));
phase_map2 = atan2(double(I4 - I3), double(I2 - I1));
% Combine the phase maps to get the unwrapped phase map
unwrapped_phase_map = unwrap2D(phase_map1, phase_map2);
% Calculate the height map using the Fourier Transform
height_map = ftp(unwrapped_phase_map);
% Display the height map
imshow(height_map, []);
```
Note: This code assumes that the fringe images are named `image1.jpg`, `image2.jpg`, `image3.jpg`, and `image4.jpg`, and are located in the same directory as the MATLAB script. Also, the `unwrap2D` and `ftp` functions are not built-in MATLAB functions and need to be implemented separately.
