3. Digital Image Processing
Chapter 1: Introduction

4. What Is Digital Image Processing?
 A sample
digital image.
662*640*256.
x
y

5.  f(x,y): A two-dimensional function,
where x and y are spatial
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.
 x size: 662, y size: 640, gray levels:
256
 Digital image: x, y, and the
amplitude values of f are all finite,
discrete quantities

6.  A sample

digital
image,

*24 bits

7.  Pixel: The elements of a digital
image.
Pixels

8.  Some applications
 FUJIFILM: Searching faces, Fuji.htm
 License plates, Licence.htm
 Tracking people, Hand.htm

9. The Origins of Digital Image
Processing
 One of the first applications of
digital images was in the newspaper
industry, when pictures were first
sent by submarine cable between
London and New York.

10.  Better quality

11.  15-tone equipment

12.  From computers, meaningful image
processing tasks appeared.

13.  Medical imaging
 Remote Earth resource observations
 Astronomy
 High-energy plasmas and electron
microscopy

14. Examples of Fields that Use Digital
Image Processing
