1.6 Image Processing Operations
It is convenient to subdivide different image processing algorithms into broad subclasses.
There are different algorithms for different tasks and problems, and often we would like to
distinguish the nature of the task at hand.
Image enhancement. This refers to processing an image so that the result is more suit-
able f or a particular application. Examples include:
• Sharpening or deblurring an out of focus image
• Highlighting edges
• Improving image contrast, or brightening an image
• Removing noise
Image restoration. This may be considered as reversing the damage done to an image
by a known cause, for example: ...
