Product Details

HelloMeme is a diffusion model integrating spatial weaving attention, aiming to embed high-fidelity and rich conditions into the image generation process. This technology generates videos by extracting the features of each frame in the driving video and using them as input to HMControlModule. By further optimizing the Animatediff module, the continuity and fidelity of the generated videos are improved. In addition, HelloMeme also supports facial expressions generated through ARKit facial blend shape control, as well as Lora or Checkpoint based on SD1.5, implementing a hot-swappable adapter for the framework that will not affect the generalization ability of the T2I model.

DreamMesh4D

DreamMesh4D

DreamMesh4D is a new framework that combines mesh representation and sparsely controlled deformation technology to generate high-quality 4D objects from monocular videos. This technique solves the challenges of traditional methods in terms of spatial-temporal consistency and surface texture quality by incorporating implicit Neural Radiation Fields (NeRF) or explicit Gaussian rendering as the underlying representation. DreamMesh4D uses inspiration from modern 3D animation pipelines to bind Gaussian drawing to triangular mesh surfaces, enabling differentiable optimization of textures and mesh vertices. The framework starts from a coarse mesh provided by a single-image 3D generation method and constructs a deformation map by uniformly sampling sparse points to improve computational efficiency and provide additional constraints. Through two-stage learning, combined with reference view photometric loss, score distillation loss, and other regularization losses, the learning of static surface Gaussians and mesh vertices and dynamic deformation networks is achieved. DreamMesh4D outperforms previous video-to-4D generation methods in terms of rendering quality and spatial-temporal consistency, and its mesh-based representation is compatible with modern geometry pipelines, demonstrating its potential in the 3D gaming and film industries.

Stable Video Portraits

Stable Video Portraits

Stable Video Portraits is an innovative hybrid 2D/3D generation method that utilizes pre-trained text-to-image models (2D) and 3D morphological models (3D) to generate realistic dynamic face videos. This technology upgrades the general 2D stable diffusion model to a video model through person-specific fine-tuning. By providing a time-series 3D morphological model as a condition and introducing a temporal denoising process, it generates a face image with temporal smoothness that can be edited and transformed into a text-defined celebrity image without additional test-time fine-tuning. This method outperforms existing monocular head avatar methods in both quantitative and qualitative analyses.

Animate3D

Animate3D

Animate3D is an innovative framework for generating animations for any static 3D model. Its core idea consists of two main parts: 1) Propose a new multi-view video diffusion model (MV-VDM), which is based on multi-view rendering of static 3D objects and trained on the large-scale multi-view video dataset (MV-Video) we provide. 2) Based on MV-VDM, a framework combining reconstruction and 4D Scored Distillation Sampling (4D-SDS) is introduced to generate animations for 3D objects using multi-view video diffusion priors. Animate3D enhances spatial and temporal consistency by designing a new spatiotemporal attention module and maintains the identity of static 3D models through multi-view rendering. In addition, Animate3D also proposes an efficient two-stage process to animate 3D models: first directly reconstructing motion from the generated multi-view video, and then refining the appearance and motion through the introduced 4D-SDS.
