arXiv:2407.19035v1 Announce Type: new Abstract: The creation of high-quality 3D assets is paramount for applications in digital heritage preservation, entertainment, and robotics. Traditionally, this process necessitates skilled professionals and specialized software for the modeling, texturing, and rendering of 3D objects. However, the rising demand for 3D assets in gaming and virtual reality (VR) has led to the creation of accessible image-to-3D technologies, allowing non-professionals to produce 3D content and decreasing dependence on expert input. Existing methods for 3D content generation struggle to simultaneously achieve detailed textures and strong geometric consistency. We introduce a novel 3D content creation framework, ScalingGaussian, which combines 3D and 2D diffusion models to achieve detailed textures and geometric consistency in generated 3D assets. Initially, a 3D diffusion model generates point clouds, which are then densified through a process of selecting local regions, introducing Gaussian noise, followed by using local density-weighted selection. To refine the 3D gaussians, we utilize a 2D diffusion model with Score Distillation Sampling (SDS) loss, guiding the 3D Gaussians to clone and split. Finally, the 3D Gaussians are converted into meshes, and the surface textures are optimized using Mean Square Error(MSE) and Gradient Profile Prior(GPP) losses. Our method addresses the common issue of sparse point clouds in 3D diffusion, resulting in improved geometric structure and detailed textures. Experiments on image-to-3D tasks demonstrate that our approach efficiently generates high-quality 3D assets.

The Future of 3D Content Creation: Combining AI and Diffusion Models
High-quality 3D assets play a crucial role in various industries, from digital heritage preservation to entertainment and robotics. Traditionally, creating these assets required skilled professionals and specialized software, but the increasing demand for 3D content in gaming and virtual reality has paved the way for accessible image-to-3D technologies. These innovations empower non-professionals to generate 3D content while reducing dependence on expert input.
However, existing methods for 3D content generation face challenges in achieving both detailed textures and strong geometric consistency. This is where ScalingGaussian, a novel 3D content creation framework, comes into play. By combining 3D and 2D diffusion models, ScalingGaussian allows for the generation of highly-detailed textures and consistent geometric structures in 3D assets.
The Process
The framework begins with a 3D diffusion model, which generates point clouds as the initial representation of the 3D asset. To enhance the denseness of the point clouds, the model selects local regions and introduces Gaussian noise. Local density-weighted selection is then utilized to refine the densification process.
In order to further refine the 3D Gaussians and improve their consistency, a 2D diffusion model with Score Distillation Sampling (SDS) loss is employed. The SDS loss guides the 3D Gaussians to clone and split, effectively enhancing their geometric structure.
Finally, the 3D Gaussians are converted into meshes, and the surface textures are optimized using Mean Square Error (MSE) and Gradient Profile Prior (GPP) losses. This ensures that the generated 3D assets not only possess detailed textures but also maintain a high level of geometric consistency.
Benefits and Implications
By addressing the common issue of sparse point clouds in 3D diffusion, ScalingGaussian significantly improves the overall quality of generated 3D assets. Its innovative approach allows for the creation of high-quality 3D content efficiently and effectively.
The implications of this framework are vast. Previously, the creation of detailed 3D assets solely relied on the expertise of professionals with access to specialized software. Now, with accessible image-to-3D technologies like ScalingGaussian, non-professionals can actively participate in the creation process.
Moreover, the convergence of AI and diffusion models opens up new possibilities for the future of 3D content creation. As this technology continues to evolve, we may witness a democratization of the industry, enabling more individuals to contribute to the development of 3D assets across various sectors.
In conclusion, ScalingGaussian revolutionizes 3D content creation by combining AI and diffusion models. Its ability to achieve detailed textures and geometric consistency in generated 3D assets paves the way for a more accessible and inclusive future in industries such as digital heritage preservation, entertainment, and robotics.

Abstract: Discerning between authentic content and that generated by advanced AI methods has become increasingly challenging. While previous research primarily addresses the detection of fake faces, the identification of generated natural images has only recently surfaced. This prompted the recent exploration of solutions that employ foundation vision-and-language models, like CLIP. However, the CLIP embedding space is optimized for global image-to-text alignment and is not inherently designed for deepfake detection, neglecting the potential benefits of tailored training and local image features. In this study, we propose CoDE (Contrastive Deepfake Embeddings), a novel embedding space specifically designed for deepfake detection. CoDE is trained via contrastive learning by additionally enforcing global-local similarities. To sustain the training of our model, we generate a comprehensive dataset that focuses on images generated by diffusion models and encompasses a collection of 9.2 million images produced by using four different generators. Experimental results demonstrate that CoDE achieves state-of-the-art accuracy on the newly collected dataset, while also showing excellent generalization capabilities to unseen image generators. Our source code, trained models, and collected dataset are publicly available at: https://github.com/aimagelab/CoDE.
Analysis of CoDE: A Novel Embedding Space for Deepfake Detection
Deepfake technology has become increasingly sophisticated, making it challenging to discern between authentic content and AI-generated fake images. While previous research has primarily focused on detecting fake faces, identifying generated natural images has recently emerged as a new area of study. In response to this, the development of solutions that utilize foundation vision-and-language models, such as CLIP, has gained traction.
However, the authors of this study argue that the CLIP embedding space, while effective for global image-to-text alignment, is not specifically optimized for deepfake detection. They propose a novel embedding space called CoDE (Contrastive Deepfake Embeddings), which is designed to address the limitations of CLIP.
CoDE is trained through contrastive learning, a method that encourages the model to learn similarities between different global-local image features. By incorporating this approach, the researchers aim to enhance the detection of deepfake images. To train the CoDE model, they generate a comprehensive dataset consisting of 9.2 million images produced by four different generators that utilize diffusion models.
The experimental results demonstrate that CoDE achieves state-of-the-art accuracy on the newly collected dataset. Additionally, the model exhibits excellent generalization capabilities to unseen image generators. This highlights the effectiveness of CoDE as a specialized embedding space tailored for deepfake detection.
The significance of this study lies in its multi-disciplinary nature, combining concepts from computer vision, natural language processing, and machine learning. By leveraging the knowledge and techniques from these fields, the authors have developed a powerful tool that contributes to the growing field of multimedia information systems.
CoDE’s implications extend beyond deepfake detection. As deepfake technology continues to advance, it becomes crucial to develop specialized tools and models that can discern between authentic and manipulated content across various domains, including animations, artificial reality, augmented reality, and virtual realities.
In the context of multimedia information systems, CoDE can aid in the development of robust and reliable systems that automatically detect and filter out deepfake content. This is particularly relevant for platforms that rely on user-generated content, such as social media platforms, online video sharing platforms, and news outlets.
Furthermore, CoDE’s potential reaches into the realms of animations, artificial reality, augmented reality, and virtual realities. These technologies heavily rely on generating realistic and immersive visual experiences. By incorporating CoDE or similar techniques, the risk of fake or manipulated content within these domains can be mitigated, ensuring a more authentic and trustworthy user experience.
In conclusion, CoDE presents a significant advancement in the field of deepfake detection, offering a specialized embedding space that outperforms previous approaches. Its multi-disciplinary nature demonstrates the intersectionality of computer vision, natural language processing, and machine learning. As deepfake technology evolves, further advancements in the detection and mitigation of fake content will be necessary across various multimedia domains, and CoDE paves the way for such developments.

Abstract: Video Question Answering is a challenging task, which requires the model to reason over multiple frames and understand the interaction between different objects to answer questions based on the context provided within the video, especially in datasets like NExT-QA (Xiao et al., 2021a) which emphasize on causal and temporal questions. Previous approaches leverage either sub-sampled information or causal intervention techniques along with complete video features to tackle the NExT-QA task. In this work we elicit the limitations of these approaches and propose solutions along four novel directions of improvements on theNExT-QA dataset. Our approaches attempts to compensate for the shortcomings in the previous works by systematically attacking each of these problems by smartly sampling frames, explicitly encoding actions and creating interventions that challenge the understanding of the model. Overall, for both single-frame (+6.3%) and complete-video (+1.1%) based approaches, we obtain the state-of-the-art results on NExT-QA dataset.
Analysis of Video Question Answering and the NExT-QA Dataset
Video Question Answering (VQA) is a complex task that requires models to not only analyze multiple frames of a video but also understand the interactions between different objects within the video. The NExT-QA dataset, introduced by Xiao et al. in 2021, places a strong emphasis on causal and temporal questions, making it an even more challenging benchmark for VQA models. Previous approaches to tackle the NExT-QA task have utilized sub-sampled information or causal intervention techniques along with complete video features. However, these approaches have their limitations, and this work aims to address and overcome these limitations through four novel directions of improvements.
1. Smart Frame Sampling
One of the limitations of previous approaches was their reliance on sub-sampled information, which could potentially miss crucial frames that provide important context for answering the questions. The proposed approach attempts to compensate for this shortcoming by adopting smart frame sampling techniques. By strategically selecting frames that contain relevant information, the model can have a more comprehensive understanding of the video and improve its performance in answering questions.
2. Explicit Action Encoding
Understanding actions and their relationships is crucial for accurately answering questions about a video. Previous approaches might have overlooked the explicit encoding of actions, which could lead to incomplete comprehension of the video content. This work recognizes the importance of explicit action encoding and proposes methods to incorporate it into the VQA model. By explicitly representing actions, the model can better reason about the temporal dynamics and causal relationships within the video, resulting in more accurate answers to temporal and causal questions.
3. Challenging Interventions
To truly test the understanding of the model, it is necessary to introduce interventions that challenge its comprehension. By creating interventions in the video that disrupt the normal course of events, the model’s ability to reason and answer questions based on causal relationships is put to the test. The proposed approach includes interventions that deliberately challenge the model’s understanding, allowing for a more robust evaluation of its capabilities.
4. State-of-the-Art Results
Through the implementation of the aforementioned improvements, this work achieves state-of-the-art results on the NExT-QA dataset for both single-frame and complete-video based approaches. This highlights the effectiveness of the proposed solutions and their ability to overcome the limitations of previous approaches. The multi-disciplinary nature of the concepts involved in this work, such as computer vision, natural language processing, and causal reasoning, underscores the complexity of the VQA task and the need for a holistic approach that incorporates insights from various fields.
In conclusion, this study addresses the challenges of video question answering, particularly in the context of the NExT-QA dataset. By strategically addressing the limitations of previous approaches and introducing novel improvements, the proposed solutions enhance the model’s reasoning ability, leading to improved performance. The multi-disciplinary nature of the concepts tackled in this work further emphasizes the need for collaboration and integration of knowledge from different domains to advance the field of video question answering.
