创新:一种前背景分离的方法
挑战:
- First, the training and testing of NeRF and NeRF++ on a single large-scale scene is quite time-consuming and memory-intensive —> NGP解决了耗时
- Second, small camera calibration errors may impede阻碍 photorealistic synthesis. Robust loss functions, such as the contextual loss (Mechrez et al., 2018), could be applied.
- Third, photometric effects such as auto-exposure and vignetting渐晕 can also be taken into account to increase image fidelity. This line of investigation is related to the lighting changes addressed in the orthogonal work of Martin-Brualla et al. (2020).
