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
