I have done that. But to get edge enhancement, hoe to calculate the dimensions of the high pass filter? How to characterize the spatial frequencies? I went through a few books but none gave a method to design filters for my purpose. Would you help me?
I am working on an experiment on Fourier optics-optical image processing. In order to get edge enhancement, how do we actually go about high pass filtering. How to design filters? How to decide the filter dimensions? Can anyone please help me?
