Abstract: The automated inspection and sorting of parts is acommon application of Machine Vision. The sorting of parts is possible only after reliable classification. Support Vector Machines (SVMs) and Artificial Neural Networks (ANNs) are popular choices as classification algorithms. Classifiers
developed from supervised algorithms perform well when trained for a specific application with known classes. Their drawback is that they are considered inflexible as they cannot be easily applied to a different application without extensive retuning. Moreover, for a given application, they do not
perform properly if there are unknown classes. Classifiers developed from semi-unsupervised algorithms can work with unknown classes but cannot work with multiple known classes. The above problem can be addressed by a hybrid two-layered approach for the classifier with a combination of supervised SVMs, semi-unsupervised SVMs and supervised ANNs. An introduction to the software package known as FlexMVS for Flexible Machine Vision System will be given that can evaluate the above hybrid approach.
