1.0 INTRODUCTION OF DIGITAL IMAGING

Digital imaging or digital image acquisition is
the creation of a digital representation of the
visual characteristics of an object

A physical scene or the interior structure of an object.

often assumed to imply or include the processing,
compression, storage, printing and display of such
images.

HISTORY OF DIGITAL IMAGING

Digital imaging was developed in the 1960s
and 1970s

largely to avoid the operational weaknesses
of film cameras, for scientific and military
missions including the KH-11 program.

As digital technology became cheaper in later
decades, it replaced the old film methods for
many purposes.

1.1 Understand the application of Digital Imaging

1.1.1 DISCUSS THE APPLICATION OF
DIGITAL IMAGING IN TODAY'S
INDUSTRIES AND LIFESTYLE

Some of the major fields in which digital image processing is
widely used are mentioned below

Image sharpening and restoration

Medical field

2. Medical field

The common applications of DIP in the field of medical is :

Gamma ray imaging

PET scan

Medical CT

UV imaging

3. Color processing

Color processing includes processing of colored
images and different color spaces that are used.

RGB color model , YCbCr, HSV.

Also involves studying transmission , storage , and
encoding of these color images.
