Alibaba presents MIMO Controllable Character Video Synthesis with Spatial Decomposed Modeling Character video synthesis aims to produce realistic videos of animatable characters within lifelike scenes. As a fundamental problem in the computer vision and graphics community, 3D works typically require multi-view captures for per-case training, which severely limits their applicability of modeling arbitrary characters in a short time. Recent 2D methods break this limitation via pre-trained diffusion models, but they struggle for pose generality and scene interaction. To this end, we propose MIMO, a novel framework which can not only synthesize character videos with controllable attributes (i.e., character, motion and scene) provided by simple user inputs, but also simultaneously achieve advanced scalability to arbitrary characters, generality to novel 3D motions, and applicability to interactive real-world scenes in a unified framework. The core idea is to encode the 2D video to compact spatial codes, considering the inherent 3D nature of video occurrence. Concretely, we lift the 2D frame pixels into 3D using monocular depth estimators, and decompose the video clip to three spatial components (i.e., main human, underlying scene, and floating occlusion) in hierarchical layers based on the 3D depth. These components are further encoded to canonical identity code, structured motion code and full scene code, which are utilized as control signals of synthesis process. The design of spatial decomposed modeling enables flexible user control, complex motion expression, as well as 3D-aware synthesis for scene interactions. Experimental results demonstrate effectiveness and robustness of the proposed method.

Interesting times in the maps space, and its exciting there is so much buzz - maps are awesome :) My parents Rakesh and Rashmi Verma pioneered digital mapping in India in 1995, returning from the US after a successful career there with the passion and desire to do something unique for India. And it’s been 20 years for me personally in the mapping space, since I was a 19-year old Stanford engineering undergraduate student and got involved in starting India’s first interactive mapping portal, I realise MapmyIndia is a relatively lesser known company amidst more consumer facing global and local players, so it would be great if this post can be amplified, so that more people can be made aware 🙏 Warm regards, Rohan Verma CEO & ED, MapmyIndia *** A few thoughts on maps: 1) Accuracy and quality of maps is critical. I’d caution folks to check out quality and reliability of maps by browsing those maps in areas familiar to them, and if they notice errors in them, in terms of incorrect places marked wrongly on the map, it should serve as a reminder not to rely on such maps. I’ve personally looked at the maps of various global and local players, and find so many inaccuracies, which confirms my belief that the difficult art and science of map-making is not as easy and people may imagine or claim. 2) What’s exciting about Mappls MapmyIndia, as a home-grown indigenous deep tech digital products and platforms company, is that not just did we pioneer digital mapping in India since 1995, when there were no other digital maps available for the country, but back then, and even now, we’ve always built the most cutting-edge tech to build the most capable maps and empower our customers, users and developers with the most comprehensive and advanced solutions. Over the last 15 or so years, there have actually been many global and local players who have come into the mapping market, yet for some reason or the other, they haven’t sustained or maintained quality. On our side we have continuously innovated in our products and tech - already bringing and making the most advanced featured available into our 4D HD maps covering 360 RealViews and 3D drone and digital twin based maps, immersive views and RealVerses - and focused on solving the needs of Indian consumers and enterprises, and served customers and users with humility, passion and consistency, with a solid and sustainable business model to ensure and provide a long-term reliable mapping solution for customers and the country. 3) Here’s an explainer video of our maps, tech & APIs which focus on how developers, users and customers can leverage our solutions to get their needs solved in the best way. Do watch - you’ll be pleasantly surprised and happy at the offering. 4) To try out as a developer for yourself, visit We’re glad that tens of thousands of developers, and their hundreds of millions of users, benefit from Mappls MapmyIndia Maps & APIs everyday, using both our free plans and our commercial plans. Do try for your own needs as a developer. 5) In one sense, the quality and capability of Mappls MapmyIndia is proven to be better and more useful and valuable through our free consumer Mappls MapmyIndia app (learn more and download from which has gotten love from millions of consumers who are able to navigate safer and better.

Want to create an avatar from a single image? FlexAvatar is a transformer model that creates full 360°, high-quality, and expressive 3D head avatar from just a single portrait image in minutes. Real-time Demo: FlexAvatar's lightweight architecture allows both animation and rendering in real-time, enabling interactive user experiences. To create a new 3D head avatar, only one image is required, e.g., from a webcam. The final avatar is ready after 2 minutes. Architecture: Under the hood, FlexAvatar adopts a transformer-based encoder-decoder design. The encoder maps the input image onto a latent avatar space, while the decoder produces 3D Gaussian attribute maps by incorporating the animation signal via cross-attention. The model learns all facial animations directly from the data without relying on pre-built 3D face models. This equips the avatars with realistic facial expressions. The internal avatar latent space can be conveniently used to integrate additional observations of a person via fitting. This enables use-cases where more than one image of a person is available, e.g., from a phone scan of the person. We train jointly on 2D monocular videos and multi-view data. However, in monocular videos, the animation signal leaks the target viewpoint, causing the model to produce incomplete 3D heads. We call this phenomenon entanglement of driving signal and target viewpoint. To prevent entanglement, we introduce bias sinks. These are learnable tokens that indicate whether a training sample stems from a monocular or a multi-view dataset. During training, the model learns to produce incomplete 3D heads only when the monocular token is present. During inference, FlexAvatar then always uses the multi-view token for which the model has learned to produce complete 3D heads. This simple design allows to combine the generalizability from monocular data with the quality of multi-view data. FlexAvatar summary: - Input: Single-image, phone scan, or monocular video - Output: Full 360° head avatar - Expressive animations - Real-time rendering and animation - Generalization to any portrait - Create a new avatar in 2 minutes - Use bias sinks to combine 2D and 3D data 🏠 🌍 🎥 Great work by Tobias Kirschstein and Simon Giebenhain!

3D-LLM: Injecting the 3D World into Large Language Models paper page: Large language models (LLMs) and Vision-Language Models (VLMs) have been proven to excel at multiple tasks, such as commonsense reasoning. Powerful as these models can be, they are not grounded in the 3D physical world, which involves richer concepts such as spatial relationships, affordances, physics, layout, and so on. In this work, we propose to inject the 3D world into large language models and introduce a whole new family of 3D-LLMs. Specifically, 3D-LLMs can take 3D point clouds and their features as input and perform a diverse set of 3D-related tasks, including captioning, dense captioning, 3D question answering, task decomposition, 3D grounding, 3D-assisted dialog, navigation, and so on. Using three types of prompting mechanisms that we design, we are able to collect over 300k 3D-language data covering these tasks. To efficiently train 3D-LLMs, we first utilize a 3D feature extractor that obtains 3D features from rendered multi- view images. Then, we use 2D VLMs as our backbones to train our 3D-LLMs. By introducing a 3D localization mechanism, 3D-LLMs can better capture 3D spatial information. Experiments on ScanQA show that our model outperforms state-of-the-art baselines by a large margin (e.g., the BLEU-1 score surpasses state-of-the-art score by 9%). Furthermore, experiments on our held-in datasets for 3D captioning, task composition, and 3D-assisted dialogue show that our model outperforms 2D VLMs. Qualitative examples also show that our model could perform more tasks beyond the scope of existing LLMs and VLMs.

Sora animates with this wonderful wonky, sketchy dreamlike quality that perfectly captures the nostalgic atmosphere of a hazy 90's suburban summer afternoon. While Seedance is just as sophisticated and in some aspects superior, I will miss the quality of Sora. Sora feels like 35mm film, with the nuanced way it captures lighting, color, and perspective, while Seedance feels digital - a bit too clean. I am confident that I can replicate this sketchy quality in Seedance by tweaking my prompts, but Sora has a unique way of animating that really should be preserved. There are many more bugs and mistakes with Sora, but when it gets it right, it REALLY hits a level of artful magic that sets it above all other models. I am shocked that I still appear to be the only person who is creating AI-Generated 2D animation with original characters while developing a unique Western style. Practically no one is doing 2D AI-animation at all, and when they do, it is usually an attempt to mimic an Anime style. 2D really should be attempted more by AI Filmmakers!! Especially with a Western model like Sora, before it is terminated in the fall. Really, everyone should be taking advantage of the way this model so skillfully animates, with the heart and soul of a seasoned professional. I personally feel AI-generated animation is superior to 3D/realistic AI filmmaking. While AI-generated realism is an attempt to mimic real life through a lens, 2D animation IS what it is - not a replica of anything, just a cartoon. I love all my AI filmmaker bros and all of the cutting edge work going on, but I urge all of you to give 2D animation a chance. : ) I'm still not giving up hope that we can save Sora somehow. Now that I see that Seedance is able to animate 2D brilliantly and beautifully, I know that it's not some hidden secret, and we can replicate the weights and maths of Sora. If we can't preserve Sora, we can make a comparable model. It's not just in the interest of AI-Animators like me to preserve this model, but in the interest of the entire American AI community if they want Western AI to be superior. If not, Chinese video models will dominate. And while I am perfectly happy to use a Chinese model and I am just eternally grateful that this technology exists at all, I would love to see American audiovisual models continue to be developed! #AIAnimation #AIFilmmaking #AIArt #SaveSora #SummerofSora #WillStancilShow Elon Musk Marc Andreessen 🇺🇸 Sora Bill Peebles NVIDIA Sam Altman
