I have a image which has periodic pattern in it. I want to retrieve the periodic pattern and display it.
I am following this procedure.
- Apply fft for the image.
- Identify the periodic frequency by using magnitude and phase spectrum
- Design a band pass filter with the periodic frequency
- Multiply the image with the designed filter
- Apply ifft for the output.
But i am not sure how to identify the periodic frequency from the spectrum ??
