Facial Recognition Advancements with Siamese Networks: A Comprehensive Survey
摘要
Face recognition is a crucial component of computer vision, finding applications in a wide range of areas from security systems to personalized user experiences. Siamese networks, a type of deep learning architecture, are a powerful approach to face recognition. These networks are designed to generate unique numerical representations, known as embeddings, for faces, enabling precise and efficient face comparison. In a Siamese network, two identical subnetworks are trained to produce similar embeddings for the same person’s face and dissimilar embeddings for different individuals. This is achieved through the training process, where the network learns to minimize the distance between embeddings of the same person while maximizing the distance between embeddings of different people. These embeddings serve as concise and meaningful representations of facial features, facilitating tasks like face verification (determining if two faces belong to the same person) and face recognition (identifying individuals from a known face database) with a high degree of accuracy. Siamese networks have demonstrated their effectiveness, particularly in scenarios where there is a limited amount of labelled data or when the goal is to recognize individuals under diverse and challenging image conditions. This approach offers a robust and versatile solution for various real-world applications, ensuring both security and convenience in the field of face recognition.
