TEDi: Temporally-Entangled Diffusion for Long-Term Motion Synthesis

no code implementations27 Jul 2023 Zihan Zhang, Richard Liu, Kfir Aberman, Rana Hanocka

The gradual nature of a diffusion process that synthesizes samples in small increments constitutes a key ingredient of Denoising Diffusion Probabilistic Models (DDPM), which have presented unprecedented quality in image synthesis and been recently explored in the motion domain.

TextDeformer: Geometry Manipulation using Text Guidance

1 code implementation26 Apr 2023 William Gao, Noam Aigerman, Thibault Groueix, Vladimir G. Kim, Rana Hanocka

Our key observation is that Jacobians are a representation that favors smoother, large deformations, leading to a global relation between vertices and pixels, and avoiding localized noisy gradients.

1 code implementation CVPR 2023 Richard Liu, Noam Aigerman, Vladimir G. Kim, Rana Hanocka

We present a neural technique for learning to select a local sub-region around a point which can be used for mesh parameterization.

NeuralMLS: Geometry-Aware Control Point Deformation

1 code implementation5 Jan 2022 Meitar Shechter, Rana Hanocka, Gal Metzer, Raja Giryes, Daniel Cohen-Or

In this work, we opt to learn the weighting function, by training a neural network on the control points from a single input shape, and exploit the innate smoothness of neural networks.

Text2Mesh: Text-Driven Neural Stylization for Meshes

1 code implementation CVPR 2022 Oscar Michel, Roi Bar-On, Richard Liu, Sagie Benaim, Rana Hanocka

In order to modify style, we obtain a similarity score between a text prompt (describing style) and a stylized mesh by harnessing the representational power of CLIP.
