Digital Image Processing
- Image enhancement techniques are heuristic procedures designed to manipulate an image in order to take advantage of the psychophysical aspects of the human system. Whereas image restoration techniques are basically reconstruction techniques by which a degraded image is reconstructed by using some of the prior knowledge of the degradation
- Image enhancement can be implemented by spatial and frequency domain technique, whereas image restoration can be implement by frequency domain and algebraic
- The computational complexity for image enhancement is relatively less when compared to the computational complexity for irrrage restoration, since algebraic methods requires manipulation of large number of simultaneous But, under some condition computational complexity can be reduced to the same level as that required by traditional frequency domain technique.
- Image enhancement techniques are problem oriented, whereas image restoration techniques are general and are oriented towards modeling the degradation and applying the reverse process in order to reconstruct the original
- Masks are used in spatial domain methods for image enhancement, whereas masks are not used for image restoration
- Contrast stretching is considered as image enhancement technique because it is based on the pleasing aspects of the review, whereas removal of’ image blur by applying a deblurring function is considered as a image restoration
