Hello,

I would like to incorporate an intensity line profile of a figure that has been created in a script. The figure is simply an fft of an image.

Thanks,

Nav

Consider going through the following MATLAB answers page:

https://www.mathworks.com/matlabcentral/answers/389889-how-to-plot-intensity-profile-of-an-image

If you want a 3-D line profile along certain defined line segments, load the image into MATLAB and use the "improfile" function to plot the intensity profile.

i1 = imread('<name of image>');
x = [19 427 416 77];    % Specify x- and y-coordinates that define connected line segments
y = [96 462 37 33];
improfile(i1,x,y),grid on;    % Display a 3-D plot of the pixel values of these line segments.
