DIGITAL SIGNAL PROCESSING (DSP)

NOISE CONCEPT

Filtering: Students need to remove the noise via filtering in the frequency domain and compute the inverse Fourier Transform to recover the noisefree image. Tasks 1) To load and extract image in Matlab. 2) Implement Fourier Transform and inverse Fourier Transform in the Matlab. 3) Perform filtering in Matlab. 4) Verify the result by showing the noisy image, Fourier transformed image, frequency response of the filter and the recovered image.

THE NOISY IMAGE IS GIVEN AS
