Paper Abstract

In the modern era of flexible manufacturing, short production runs and strict quality requirements, flexible easily trained inspection systems are essential. It is no longer unusual to have lines in which the product changes several times a shift. In such circumstances inspection system setup and retraining times of the order of a couple of minutes or less may be required. There is a large class of assembly and packaging processes which require verification that the correct components are present in the corrected locations. In many of these applications the relative proportion of different colors in a particular region can be used as the basis of inspection. Since the color distributions are generally complex and defy simple descriptions, train by showing is the only practical solution. The 'minimum description' paradigm, which uses a full 3-dimensional color space without the information loss inherent in color coordinate transformations or separation, provides a key to easy robust automation of this type of inspection.
