Can you suggest a book or articles for those with no technical that explains how computer vision systems work?

Hi Ruth; I find one of the best starting points for machine vision basics is offered up through the Certified Vision Professional program managed by the AIA. If you check out the online basic program videos and references, that is a great place to start. When I hire a new intern or engineer just out of school, this is my starting point to get them introduced to the field. Steve W.
