  name: SC-NeRF
  description: >
    SC-NeRF is a dataset designed for 3D reconstruction using Neural Radiance Fields (NeRF) under a 
    stationary-camera setup. It targets high-throughput plant phenotyping in controlled indoor environments, 
    simplifying the traditional NeRF pipeline that requires a moving camera around static objects. 
    Instead, it uses a rotating object in front of a stationary camera, making it practical for automated 
    phenotyping systems. The dataset includes videos, extracted frames, COLMAP pose estimations, trained NeRF 
    models, and high-resolution point clouds for six agriculturally relevant objects.
