Image Processing and Analysis


How do we „see“ things ?

What can you „see“ here ?

And here ?

Try again …

Some Terms …

Image Processing: low level operations;
output is still an image.

Image Analysis: still low level; output is not
longer an image (numbers, …).

Machine Vision: high level applications;
simulates human vision.

Pattern Recognition: REcognition and
classifying of patterns (not only IP!).

Examples: Image Processing

Examples: Image Analysis

Examples: Machine Vision

What do we expect from a
Machine Vision System ?

… to „see“ things like we (humans) do;

Therefore: we need some knowledge and
understanding about how we see things;

… and we have to „think“ like a Machine
Vision system.

Why do we use cameras as sensors ?

Cameras are getting cheaper and cheaper;

Computer are getting cheaper and cheaper;

Software is getting more and more powerful;

The combination of


Computer, and


is a cost
effective measuring system, which can be
used for a large number of applications.
