FrugalNeRF: Fast Convergence for Extreme Few-shot Novel View Synthesis without Learned Priors

Neural Radiance Fields (NeRF) face significant challenges in extreme few-shot scenarios, primarily due to overfitting and long training times. Existing methods, such as FreeNeRF and SparseNeRF, use frequency regularization or pre-trained priors but struggle with complex scheduling and bias. We intro…
