Fields that use Digital Image
Processing?
• Answer is….Everywhere (Almost)
• Today, there is almost no area of technical
endeavor that is not impacted in some way by
DIGITAL IMAGE PROCESSING.
Why Digital Image Processing?
• Principal Applications Areas-
– Improvement of pictorial information for human
interpretations
– Processing of image data for storage,
transmission and representation for autonomous
machine/computer perception.

Imaging: Microwave and Radio Band
• Continuous quality control offers
an advantage in terms of process
safety in liquids as well as solids.
The microwave imaging therefore
guarantees for quick and safe
monitoring and reduces the
rejects rate in production
