MULTIMODAL 2D/3D/4D AVATAR GENERATION AND EDITING: A SURVEY
PhD Qualifying Examination Title: "MULTIMODAL 2D/3D/4D AVATAR GENERATION AND EDITING: A SURVEY" by Mr. Hongyu LIU Abstract: The creation and animation of digital avatars have become a cornerstone of modern AI-Generated Content (AIGC), with profound implications for virtual reality (VR), the metaverse, digital communication, and the entertainment industry. Synthesizing photorealistic and controllable avatars that can be animated across 2D, 3D, and 4D modalities presents a significant and multifaceted challenge. Propelled by the rapid advancements in deep generative models, the field of avatar synthesis has witnessed remarkable progress in recent years. This survey provides a comprehensive review of modern approaches for multimodal 2D, 3D, and 4D avatar generation and editing.
