Are Multi-view Edges Incomplete for Depth Estimation? Numair Khan,Min H. Kim, James Tompkin International Journal of Computer Vision (IJCV), 2023 paper /bibtex This work shows that multi-view edges can encode all relevant information for depth reconstruction. For this, we follow Elder’s complementary work on the completeness of 2D edges for image reconstruction. |
