Chapter - 5 Image Enhancement - IGNTU

Chapter - 5 Image Enhancement 83 Chapter 5 Image Enhancement Introduction An Overview Image Enhancement is the improvement of satellite Image quality without knowledge about the source of degradation. If the source of degradation is known, one calls the process Image restoration previously discussed in chapter3 Both are iconical processes, viz., input and output is images. Many different, often elementary and heuristic methods are used to improve images in some sense. Image restoration removes or minimizes some known degradations in an Image . In many Image processing applications, geometrical transformations facilitate processing.
