Photometric consistency loss
WebAug 31, 2024 · Unlike geometric consistency, photometric consistency requires reconstructing the 3D geometry because the color of a 3D point is valid only if it is visible from the current perspective. In our work, we use a neural radiance field to reconstruct the 3D occupancy and color. This implicit representation is differentiable through both … WebApr 7, 2024 · The key challenge in learning dense correspondences lies in the lack of ground-truth matches for real image pairs. While photometric consistency losses provide unsupervised alternatives, they struggle with large appearance changes, which are ubiquitous in geometric and semantic matching tasks. Moreover, methods relying on …
