Digital image processing is the use of computer algorithms to perform image processing on digital images. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing. Since images are defined over two dimensions (perhaps more) digital image processing may be modeled in the form of multidimensional systems.
Famous quotes containing the word image:
“Lear. Thou hast seen a farmer’s dog bark at a beggar?
Gloucester. Ay, sir.
Lear. And the creature run from the cur? There thou mightst behold the great image of authority: a dog’s obeyed in office.”
—William Shakespeare (1564–1616)
