2. What is an image ?
 An image is a spatial representation of a two-
dimensional or three-dimensional scene.
 An image is an array, or a matrix pixels
(picture elements)arranged in columns and
rows

6. What is a digital image?
 An image may be defined as a two-
dimensional function, f(x, y),
 where x and y are spatial (plane)
coordinates, and the amplitude of f at any
pair of coordinates (x, y) is called the
intensity or gray level of the image at that
point.

7. What is a digital image?
 Digital Image:
When x, y and the intensity values of f are all
finite, discrete quantities, we call the image a
digital image.
 Color image
The field of digital image processing refers to
processing digital images by means of a digital
computer7
