DIP Quiz - Enhancement in FD & Segmentation

The Fourier transform represents an image in terms of its __________ and __________ components.

(a)  

High-frequency components in an image correspond to (a)   details such as edges and noise.

A (a)   pass filter allows low frequencies to pass and blocks high frequencies.

In contrast, a (a)   pass filter blocks low frequencies and allows high frequencies.

The (a)   Fourier Transform is used to convert an image from the spatial domain to the frequency domain.

The center of the frequency domain representation corresponds to the (a)   frequency components.

A Butterworth filter provides a (a)   transition between passed and blocked frequencies.

Ideal filters often cause (a)   in the spatial domain due to their sharp cut-off.

The process of enhancing an image in the frequency domain by removing high-frequency noise is typically done using a (a)   pass filter.

To enhance edges in the frequency domain, a (a)   pass filter is applied to the image.
