Example of the above table usage: if the user wants to find the best shots in his application, he needs to look at the "Best Shot Selection" column and see what network models and structures are required to run such functionality.The required models and structures are marked with green. Algorithms and structures marked with red are not used for the functionality.

The <version> placeholder shows that there can be several versions of the NN in distribution.

The <device> placeholder shows that the model can be used with different devices (e. g., CPU, GPU). The name of the model includes corresponding postfix (e. g., *_cpu.plan, *_gpu.plan). See "Hardware requirements" section in "FaceEngine Handbook" for information about devices supported by NN.

To decide what type of detector model to use in your specific use case (FaceDet_* networks) please refer to "FaceEngine Handbook" chapter "Face Detection Facility".

You should select one of the extraction CNNs listed in this table. See "FaceEngine Handbook" "Appendix A. Specification" for information about their performance and chapter "Descriptor Processing Facility" for information about CNNs.

You don't have to use both ordinary and mobilenet version for descriptor (cnn* networks), it's enough to choose one of these models. For details on difference see "FaceEngine Handbook" chapter "Descriptor Processing Facility".

"No additional plans are required" means that the feature is implemented without NN usage.
