Deformable Neural Radiance Fields (Nerfies) reconstruct 3D scenes from collections of casual photos by learning neural implicit representations. The method extends NeRF to handle non-rigid deformations, enabling reconstruction of deformable objects like captured selfie videos. Built on JAX and JaxNeRF, the codebase supports training custom Nerfie models using GPUs or Cloud TPUs, with Colab notebooks provided for easy experimentation.
