EigenFace 256 Dataset Construction Training a robust face embedding model requires a diverse dataset with multiple images per identity—capturing variations in angles, lighting, expressions, and age. Using real world data for this purpose poses several challenges: Privacy and Ethics : Real world images can lead to legal and ethical complications. Bias and Imbalance : Datasets based on real images may lack diversity. Data Labeling Complexity : Annotating large datasets is time consuming and costly. Synthetic Approach To overcome these issues, we built EigenFace 256, a fully synthetic dataset designed to maintain consistent identity across controlled variations. Key features include: Controlled Variations : Multiple images per identity with different angles, lighting, and expressions. Age Diversity : Variations that allow models to generalize across different life stages. Ethically Sound : 100% synthetic images, eliminating privacy concerns. Balanced Data : Diverse training samples to reduce demographic bias. Unlike many synthetic datasets that generate single image identities, EigenFace 256 provides multiple controlled variations per identity, contributing to more robust embeddings.
