Generalized Binary Search Network for Highly-Efficient Multi-View Stereo

1 code implementation CVPR 2022 Zhenxing Mi, Di Chang, Dan Xu

The new formulation makes our method only sample a very small number of depth hypotheses in each step, which is highly memory efficient, and also greatly facilitates quick training convergence.
