I have converted an image into frequency domain using fft2() function. Now I want to extract only the high frequency components. How to solve this?

Use the app for filter design.
But first define what is high frequency for your case? For example in my project all signal over 10Hz is defined as High-frequency, in other applications it refeers to components over 10KHz.
