Write the steps involved in frequency domain filtering

Answer 1

I hope that this will help you

Answer 2

By adjusting the frequencies of components, the image texture adjusting process is the frequency domain filtering.

• We can make the image texture soften and sharpen by removing low or high-frequency components.
• The frequency-domain filtering is used for this purpose.
• The main focus of frequency domain filtering is smoothening and sharpening.
• This process includes mainly 6 steps.
• First, need to collect the padding elements of the image.
• Using padding find out the Fourier transform of the image.
• Create a filter function for the image.
• Then have to obtain the multiplication product of the transformed image and the filter.
• Then need to find that product's inverse FFT.
• Need to adjust the image to its original size.
