2. Digital Image Processing
 Digital image processing can be define as
processing digital image in digital manner
meaning that uses digital device like computer
etc.
 The digital image processing is getting more and
more importance now a days because of its two
major application areas:
1)Improvement of pictotial information for human
interpretation.
2) Processing of image data for storage,
transmission, and representation for autonomous
machine preception.

3. History: How does it Started
 American Jet Propulsion Laboratory (JPL)
happened to be the first successful application
in 1960s. Using this, in 1964, Space Detector
Ranger 7 sent thousands of lunar photos.
They mainly used image processing
techniques like geometric correction,
gradation transformation, and noise removal
on the sent lunar photos.

5. Working principle
 Digital image processing deals with manipulation
of digital images through a digital computer. It is a
subfield of signals and systems but focus particularly
on images. ... The input of that system is a digital
image and the system process that image using
efficient algorithms, and gives an image as an output.

6. Steps in Image Processing
 Image Acquisition
 Image Enhancement
 Image Restoration
 Colour Image Processing
 Compression

7. Applications
 The use of digital image processing technique
has explored and they are now used for all
kind of tasks in all kainds of areas:
 Image Enhancement
 Artistic Effects
 Medical Visualisation
 Law Enforcement
 Human Computer Interface
 Space applications
