- NeuralField-LDM Scene Generation with Hierarchical Latent Diffusion Models (17 Aug 2023)
This is my reading note on NeuralField-LDM Scene Generation with Hierarchical Latent Diffusion Models. It trains auto-encoder to project RGB images of scene with camera pose into the latent space (voxel-nerf). It uses three levels of latent to represent the scene and then uses hierarchical latent diffusion model to represent it.
- pixelNeRF Neural Radiance Fields from One or Few Images (26 Sep 2022)
pixelNeRF: Neural Radiance Fields from One or Few Images tries to learn a discontinuous neutral scene representation from one or few input images. To this end, pixelNeRF introduced an architecture that conditions a NeRF on image inputs in a fully convolutional manner. This allows the network to be trained across multiple scenes to learn a scene prior, enabling it to perform novel view synthesis in a feed-forward manner from a sparse set of views (as few as one).
