Questions and Answers

What is the main objective of image enhancement?

  • To make the image more blurry
  • To make the image look darker
  • To highlight certain features and make the resulting output suitable for a specific application (correct)
  • To reduce the details in the image

    • In which domain do spatial domain methods for image enhancement operate?

  • Time domain
  • Frequency domain
  • Spatial domain (correct)
  • None of the above

    • What is the primary difference between spatial domain methods and frequency domain methods for image enhancement?

  • There is no difference between spatial domain and frequency domain methods.
  • Frequency domain methods look at pixel change rate, while spatial domain methods operate on the spectral component of the image.
  • Frequency domain methods focus on the time domain, while spatial domain methods focus on the frequency domain.
  • Spatial domain methods modify the Fourier Transform of an image, while frequency domain methods directly manipulate pixels in the image. (correct)
