The field of generative modeling and animation is rapidly evolving, with a focus on creating more realistic and controllable digital avatars. Recent developments have led to significant improvements in photorealism, expression editing, and pose-dependent deformations. The use of diffusion models, Gaussian morphable models, and neural rendering has enabled the creation of high-fidelity digital avatars that can be used in various applications, including virtual try-on, animation, and video production. Noteworthy papers in this area include Face-MoGLE, which introduces a novel framework for controllable face generation, and Hyper Diffusion Avatars, which proposes a method for dynamic human avatar generation with high photorealism and realistic pose-dependent deformations. Additionally, papers such as Durian and Reconstruction and Reenactment Separated Method for Realistic Gaussian Head have made significant contributions to the field of portrait animation and 3D Gaussian head reconstruction.
