What is the main objective of image enhancement?
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?
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?
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)
