Note that in terms of novel view synthesis, our method demonstrates similar performance compared to TensoIR and GS-IR. This is because these baselines tend to overfit the training dataset and bake the complex lighting effects (eg. shadows) within the materials, as qualitatively analyzed above. Despite this, we can produce considerably better material estimation and relighting results.
This video will explain our motivation and each stage of the pipeline, and showcase our results.
