What are ways to prevent Gibbs phenomenon?

The Gibbs phenomenon in a filtered image can be reduced by partitioning the image so that the amplitude of the discontinuity is controlled. The proposed method is efficient and simple in implementation, with fast Fourier transform.

Can you get rid of Gibbs phenomenon?

The Gibbs phenomenon in the Fourier transform is due to a periodicity discrepancy between the waveform and its sinusoidal representations in the time domain. Data flipping, baseline tilting, or digital comparison completes the periodicity of the waveform and thus removes the Gibbs phenomenon.

What is Gibbs phenomenon why it occurs What are the ways to prevent it?

For a periodic signal with discontinuities, if the signal is reconstructed by adding the Fourier series, then overshoots appear around the edges. These overshoots decay outwards in a damped oscillatory manner away from the edges. This is known as GIBBS phenomenon and is shown in the figure below.

What causes the Gibbs phenomenon?

3. What causes the gibbs phenomenon? Explanation: In case gibbs phenomenon, When a continuous function is synthesized by using the first N terms of the fourier series, we are abruptly terminating the signal, giving weigtage to the first N terms and zero to the remaining. This abrupt termination causes it.
