Presently Iam working on 2D FFT.I have read in few papers that most of the fft energy is stored in lower order coefficients hence planned to low pass the FFT signal.Iam not getting good no. of zerosin filtered o/ps.
Again in few papers it has been said that eyes are not sensitive to high frequencies and hence those frequencies can be removed(Not sure whether frequency coefficients of transform domain or input signal frequncies in spatial domain). Iam bilwered!So suggest me how to proceed which is better?
 

That means that higher order Fourier coefficients can be lost without significant loss of quality in the reconstructed signal or image.
Those coefficients don't need to be stored or transmitted, resulting in data compression.
