Wheels identification using machine vision technology
Shabestari, Miller, Wedding · 1991
An application of an online vision system using statistical pattern recognition algorithms for identifying various polycast wheels is described. The recognition is independent of part orientation and position in camera field of view. Simplicity, efficiency, low cost, and easy training for new designs are important criteria of the system. Software and algorithms to locate the wheel, exclude the windows of the wheel, and extract features which are used for classification are developed. The results indicate a constraint-free system with real-time recognition rate and considerable increase in recognition accuracy.>
