Technological complexity: smart search, which takes into account additional parameters when ranking similar faces of employees; development of its own workflow of a cascade of neural networks and machine learning algorithms to quickly find matches for all faces in the frame, detection and 3D reconstruction for image alignment and verification of permissible limits for triggering facial rotation recognition (increased accuracy, reduced errors). Similar approach is applied in their products by market leaders specializing in face recognition and identification (e.g., VisionLabs).
