演讲主题及嘉宾介绍
1、Drag Your GAN: Interactive Point-based Manipulation on the Generative Image Manifold
议题简介：Synthesizing visual content that meets users' needs often requires flexible and precise controllability of the pose, shape, expression, and layout of the generated objects. Existing approaches gain controllability of generative adversarial networks (GANs) via manually annotated training data or a prior 3D model, which often lack flexibility, precision, and generality. In this talk, we will introduce a powerful yet much less explored way of controlling GANs, that is, to "drag" any points of the image to precisely reach target points in a user-interactive manner. To achieve this, we propose DragGAN, which consists of two main components including: 1) a feature-based motion supervision that drives the handle point to move towards the target position, and 2) a new point tracking approach that leverages the discriminative GAN features to keep localizing the position of the handle points. Through DragGAN, anyone can deform an image with precise control over where pixels go, thus manipulating the pose, shape, expression, and layout of diverse categories such as animals, cars, humans, landscapes, etc. As these manipulations are performed on the learned generative image manifold of a GAN, they tend to produce realistic outputs even for challenging scenarios such as hallucinating occluded content and deforming shapes that consistently follow the object's rigidity.

2、Machine Learning for 3D Content Creation
议题简介：With the increasing demand for creating large-scale 3D virtual worlds in many industries, there is an immense need for diverse and high-quality 3D content. Machine learning is existentially enabling this quest. In this talk, I will discuss how looking from the perspective of combining differentiable iso-surfacing with differentiable rendering could enable 3D content creation at scale and make real-world impact. Towards this end, we first introduce a differentiable 3D representation based on a tetrahedral grid to enable high-quality recovery of 3D mesh with arbitrary topology. By incorporating differentiable rendering, we further design a generative model capable of producing 3D shapes with complex textures and materials for mesh generation. Our framework further paves the way for innovative high-quality 3D mesh creation from text prompt leveraging 2D diffusion models, which democretizes 3D content creation for novice users.

4、Image, Video and 3D Content Creation with Diffusion Models
议题简介：Denoising diffusion-based generative models have led to multiple breakthroughs in deep generative learning. In this talk, we will provide an overview over recent works by NVIDIA on diffusion models and their applications for image, video, and 3D content creation. We will start with a short introduction to diffusion models and then discuss large-scale text-to-image generation. Next, we will highlight different efforts on 3D generative modeling. This includes both object-centric 3D synthesis as well as full scene-level generation. Finally, we will discuss our recent work on high-resolution video generation with video latent diffusion models. We turn the state-of-the-art text-to-image model Stable Diffusion into a high-resolution text-to-video generator and we also demonstrate the simulation of real in-the-wild driving scene videos.
