Recognizer Types
Object Class Recognition supports several types of recognizer. All use neural networks but have different characteristics.
OpenText recommends that you train object class recognition on a machine with a supported GPU. You can use a trained recognizer with or without a GPU but OpenText recommends using a GPU for best performance.
Generation4recognizers offer the best accuracy, especially for recognizers that you train yourself. TheGeneration4recognizer type was introduced in Media Server 12.9.Generation3recognizers are the fastest at run-time, but accuracy is slightly lower than aGeneration2orGeneration4recognizer.Generation2recognizers were introduced in Media Server 12.4 and OpenText now recommends usingGeneration4recognizers instead.
