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 –Camera, –Computer, and –Software –is a cost-effective measuring system, which can be used for a large number of applications.
