Overview of 3D Human Face Reconstruction Techniques and a Novel Approach

Three-dimensional (3D) human face reconstruction methods have gained significant attention in recent years due to their diverse applications in fields such as entertainment, biometrics, healthcare, and cyber security. This survey presents an overview of existing 3D human face reconstruction methods, highlighting their principles, techniques, and advancements. The survey covers various approaches including photometric stereo, structured light, shape-from-shading, and multi-view stereo methods. Each method's strengths, limitations, and potential applications are discussed, providing insights into their suitability for different scenarios. This survey examines the challenges faced by these methods, such as occlusions, variations in lighting conditions, and facial expressions. Promising research directions and emerging trends in 3D human face reconstruction are also explored, including real-time applications, personalized models, cross-domain integration, and ethical considerations. Additionally, this work also presents our preliminary work in a 3D precise human face reconstruction. This work serves as a comprehensive resource for researchers, practitioners, and industry professionals seeking to understand the state-of-the-art in 3D human face reconstruction and its potential for future advancements.
