Researchers have introduced a new benchmark and detector for identifying fake 3D Gaussian heads reconstructed from single portraits. Existing methods struggle with retaining fine-grained information and maintaining feature consistency across different rendered views. The proposed detector addresses these limitations through a two-stage training strategy, utilizing masked autoencoding for fine-grained information retention and multi-view contrastive learning for feature consistency. Experiments demonstrate that this novel approach achieves superior accuracy and performance across all evaluated metrics. AI
