V3D: Video Diffusion Models are Effective 3D Generators
This approach focuses on leveraging pre-trained video diffusion models for generating high-fidelity 3D objects and scenes from single or sparse 2D images, significantly speeding up the generation process while maintaining or enhancing detail quality.
Key highlights from the document include:
Introduction of V3D: V3D stands out by utilizing video diffusion models for 3D object and scene generation, addressing the challenge of generating detailed objects at speed. It extends video diffusion models to 3D generation by introducing geometrical consistency priors and fine-tuning on 3D datasets.
Technological Advancements: The approach encompasses several innovations, such as a reconstruction pipeline tailored for video diffusion outputs, enabling the rapid creation of high-quality meshes or 3D Gaussians. V3D also shows capabilities in scene-level novel view synthesis, providing control over camera paths with sparse input views.
Experimental Validation: The paper includes comparisons with state-of-the-art methods across various benchmarks, showing V3D’s superior performance in terms of generation quality and consistency. The approach demonstrates significant improvements over existing methods in speed, detail, and multi-view consistency.
Open-Source Contribution: The authors have made their code available, encouraging further research and application development in the field of 3D generation.
A Million-scale Real Prompt-Gallery Dataset for Text-to-Video Diffusion Models
The paper introduces VidProM, a pioneering dataset specifically created for text-to-video diffusion models.
This extensive dataset comprises 1.67 million unique text-to-video prompts sourced from real users, alongside 6.69 million videos generated through four advanced diffusion models.
VidProM opens up new research opportunities by facilitating the study of Text-to-Video Prompt Engineering, Efficient Video Generation, Fake Video Detection, and Video Copy Detection for diffusion models.
Key highlights include:
VidProM’s Uniqueness: The dataset stands out as the first of its kind, emphasizing the importance of tailored prompts for text-to-video generation and providing insights into user preferences in video creation. It’s significantly larger and more diverse than existing datasets, like DiffusionDB, which focuses on text-to-image prompts.
Research Implications: The dataset not only aids in the evaluation and development of text-to-video models but also encourages exploring new methodologies for prompt engineering and efficient video generation. Moreover, it addresses the need for safer models by contributing to fake video detection and copyright issues through video copy detection.
Creation Process and Dataset Details: The paper details the meticulous process of assembling VidProM, including the extraction and embedding of prompts, assigning NSFW probabilities, and the generation and collection of videos. It also introduces VidProS, a subset containing semantically unique prompts to ensure high diversity.
Comparison with DiffusionDB: A comprehensive analysis reveals significant differences between VidProM and DiffusionDB, particularly in the semantic uniqueness of prompts, the methodologies of embedding, and the overall scope and depth of the collected data.
Analysis of User Preferences: By examining the content of the prompts, the research identifies prevalent themes and topics of interest among users, such as modernity, motion, and natural elements, indicating the types of videos most sought after for generation.
Future Directions: The dataset not only serves as a foundation for improving text-to-video diffusion models but also proposes novel research avenues in prompt engineering, video generation efficiency, and multimedia learning tasks leveraging synthetic video content.
Overall, VidProM represents a significant contribution to the field of text-to-video generation, providing a rich resource for developing more advanced and efficient models, while also highlighting the evolving landscape of user preferences and the potential for new research explorations.
FaceChain-SuDe: Building Derived Class to Inherit Category Attributes for One-shot Subject-Driven Generation
This approach treats a subject as a derived class from its semantic category, allowing it to inherit public attributes while learning private ones from user-provided examples. The method, named Subject-Derived regularization (SuDe), constrains subject-driven generated images to semantically belong to the subject’s category, significantly improving attribute-related generations and maintaining subject fidelity.
Dataset and Prompts
The dataset used includes 30 subjects across 15 categories from the DreamBench dataset, with one example image per subject.
Five attribute-related prompts were created for each subject, tailored to specific characteristics like color, action, and material.
Limitations and Failure Cases
SuDe inherits the inherent limitations of the stable-diffusion backbone, such as difficulty in preserving text characters on subjects and addressing indirectly related attributes like wearing clothes not typically associated with the subject (e.g., a dog wearing a shirt).
Experimental Results and Comparisons
SuDe shows stable improvement in attribute alignment without compromising subject fidelity across different baselines and versions of Stable Diffusion.
It outperforms both online and offline methods, offering a plug-and-play solution that can be easily integrated with existing frameworks.
More Experimental Results
SuDe can handle a range of applications beyond simple attribute editing, such as recontext visualization, art renditions, and action editing, demonstrating its versatility and broad applicability.
It also shows promise in generating images with a variety of subjects and attributes, including objects, animals, cartoons, and human faces.
