Diffusion models have been successfully applied to point cloud generation tasks recently. The main notion is using a forward process to progressively add n
We propose FrePolad: f requency- re ctified po int la tent d iffusion , a point cloud generation pipeline integrating a variational autoencoder (VAE) with a denoising diffusion probabilistic model (DDPM) for the latent distribution. FrePolad simultaneously achieves high quality, diversity, and...
Denoising diffusion models (DDMs) have shown promising results in 3D point cloud synthesis. To advance 3D DDMs and make them useful for digital artists, we require (i) high generation quality, (ii) flexibility for manipulation and applications such as conditional synthesis and shape interpolation, ...
A hierarchical diffusion model is then fit to the latents to complete the scene generation pipeline. We achieve a substantial improvement over existing state- of-the-art scene generation models. Additionally, we show how NeuralField-LDM can be used for a variety ...
this script trains model for single-view-reconstruction or text2shape task the idea is that we take the encoder and decoder trained on the data as usual (without conditioning input), and when training the diffusion prior, we feed the clip image embedding as conditioning input: the shape-...

The open source Stable Diffusion [70] is a case in point, since removing the watermark amounts to commenting out a single line in the source code. Our Stable Signature method merges watermarking into the generation process itself, without any architectural change...
