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:
“The places we have known do not only belong to the world of space in which we situate them for the sake of simplicity. They were but a thin slice between contiguous impression which formed our lives back then; the memory of a certain image is but the regret of a certain instant; and the houses, the roads, the avenues are fleeting, alas! as the years.”
—Marcel Proust (1871–1922)
