Recently, I saw a method that we can obtain a spatial frequency component of the stereoscopic images by applying the Sobel operation. But I don't understand how to get the spatial frequency component. Who can tell me how?
Hi Lihui Cao. To obtain the frequency distribution you can do Fourier Transform using Matlab.
The function is called "fft" and also have to use the "fftshift". If what you need is to represent the transform module use "abs".
The Matlab is very didactic and I recommend it.
I hope this will be of some.

Dear Cao,
It would better if you try this using MATLAB. However, I don't have any direct answer for you but may be given link can help you. I also attached a research paper for you that would be helpful for you.
