Topic 1 - Introduction

DIGITAL IMAGE PROCESSING

Course 3624

Department of Physics and Astronomy

Professor Bob Warwick

Why is DIP relevant?

• The analysis of data in the form of images is an increasingly important and relevant topic in many areas of science including medicine, remote sensing, astronomy etc..

• Image capture, manipulation & transmission is also a key component of many modern technologies.

• Digital images are now a common feature of modern life eg the internet, telephones, home photography

Applications of DIP

• Telecommunications (Internet, video phones)

• Broadcasting (digital TV)

• Surveillance (security systems, law enforcement)

• Medical Imaging

• Machine vision (guidance, control, robotics....)

• Remote Sensing of the Earth

• Space Exploration

• Astronomy

• etc..

About This Course

• This course serves as a primer to the techniques of digital image processing (DIP) and their implementation.

• It looks at the principles and theory on which DIP techniques are based – it is NOT a practical course in the subject.

• Course slides are available from my web page at: http://www.star.le.ac.uk/~rsw
