WebJun 9, 2024 · FFT is an algorithm that computes the Discrete Fourier Transform (DFT) or Inverse Discrete Fourier Transform (IDFT) from original domain to frequency domain and do the required manipulation in order to reduce noise and try to remove noise. FFT is majorly applied for Signal processing. In this project we will attempt to de-noise images also.
