Face Detection in the Wild: Techniques, Applications, and Future Directions
Downloads
Face detection is fundamental to computer vision, allowing for applications in human-computer interaction, healthcare, surveillance, and authentication. Deep learning-based frameworks have recently replaced traditional handcrafted models, providing excellent accuracy, real-time performance, and robustness in a variety of scenarios, including poor lighting and occlusion. The use of face detection in embedded and edge devices has increased because to lightweight models and mobile-optimized systems. The detection of small or modified faces, maintaining demographic fairness, and resolving ethical issues like algorithmic bias and privacy are still difficulties, though. Explainable AI, multimodal integration, and context-aware systems are probably going to be the main areas of future research to provide face detection technologies that are more transparent, inclusive, and trustworthy.
