Combining 3D Morphable Models: A Large scale Face-and-Head Model is a research paper that proposes a method to combine existing 3D Morphable Models (3DMMs) of face and head shapes to create a larger and more diverse model. The authors argue that existing 3DMMs suffer from limited variation due to the small number of samples used to create them, and that combining multiple models can this limitation.
The proposed method involves aligning the different 3DMMs using a common reference frame, and then merging them into a single model. To ensure that the resulting model is still statistically representative of the population, the authors use a weighting scheme that takes into account the relative size of each dataset and the variance within each dataset.
The final model is evaluated on several tasks, including face recognition and 3D face reconstruction from a single image. The results show that the combined model outperforms existing models in terms of accuracy and diversity.
Overall, the paper presents a promising approach to creating more comprehensive 3DMMs that can better capture the variability of human faces and heads.
