  1. EER of the proposed identification algorithm if alignment was applied using manually annotated markings, automatically detect markings, or if no alignment was applied as a pre-processing step. The EER for manually annotated markings and automatically detected feature points are very close while the performance of the algorithm drops significantly if no alignment was performed at all.
