Question

Choose the CORRECT statement(s).

• A. Higher frequencies in an original image predominantly appear around the center of its Fourier Spectrum.
• B. Higher frequencies in an original image predominantly appear progressively along the outer edge of its Fourier Spectrum.
• C. Horizontal features in an original image appear as vertical components in its Fourier Spectrum.
• D. Vertical features in an original image appear as vertical components in its Fourier Spectrum.

Hint:

In the Fourier Spectrum of an image, low frequencies are at the center and high frequencies are at the outer edges, with spatial features in the image corresponding to orthogonal components in the spectrum.

Answer 1

The Correct Option is B, C

- Option (A) is incorrect because higher frequencies in the Fourier Spectrum of an image typically appear at the outer edges, not the center. The center represents low frequencies.
- Option (B) is correct because higher frequencies are located at the outer edges of the Fourier Spectrum, while lower frequencies are at the center.
- Option (C) is correct because in the Fourier Transform of an image, horizontal features correspond to vertical components in the Fourier Spectrum (and vice versa for vertical features).
- Option (D) is incorrect because vertical features in the image are represented as horizontal components in the Fourier Spectrum, not vertical ones. Step 1: Conclusion
The correct answers are (B) and (C).
