Explain how image enhancement is better in the frequency domain as compared to spatial domain

In digital image processing, image enhancement techniques can be broadly categorized into spatial domain and frequency domain methods. Both domains offer different advantages, but enhancement in the frequency domain often proves to be more effective for certain applications due to several key reasons.

Spatial Domain vs. Frequency Domain:

1. Spatial Domain Techniques:
   - These techniques operate directly on the pixel values of an image. Common methods include histogram equalization, spatial filtering (such as smoothing and sharpening filters), and contrast adjustment.
   - Spatial domain methods are intuitive and straightforward, often involving operations like convolution with masks. _________ _________ ____ __________ ________ _____ __________ ______ ___ ____ _____.
