, WHAT IS DIGITAL IMAGE PROCESSIN
• An image may be defined as a two-dimensional function,
f(x, y)
where, x and y → spatial (plane) coordinates,
amplitude of f at any pair of coordinates (x, y) is called the
intensity or gray level of the image at that point.
• When x, y, and the amplitude values of f are all finite, discrete quanti
the image is a digital image.
• Digital image processing refers to the field of processing digital ima
by means of a digital computer. Ms. Siddhi P. Naik

elements, which has a location and value
