Exploiting Correspondences with All-pairs Correlations for Multi-view Depth Estimation

no code implementations5 May 2022 Kai Cheng, Hao Chen, Wei Yin, Guangkai Xu, Xuejin Chen

However, multi-view depth estimation is fundamentally a correspondence-based optimization problem, but previous learning-based methods mainly rely on predefined depth hypotheses to build correspondence as the cost volume and implicitly regularize it to fit depth prediction, deviating from the essence of iterative optimization based on stereo correspondence.

Sliced gradient-enhanced Kriging for high-dimensional function approximation

no code implementations5 Apr 2022 Kai Cheng, Ralf Zimmermann

Gradient-enhanced Kriging (GE-Kriging) is a well-established surrogate modelling technique for approximating expensive computational models.

Towards 3D Scene Reconstruction from Locally Scale-Aligned Monocular Video Depth

no code implementations3 Feb 2022 Guangkai Xu, Wei Yin, Hao Chen, Chunhua Shen, Kai Cheng, Feng Wu, Feng Zhao

However, in some video-based scenarios such as video depth estimation and 3D scene reconstruction from a video, the unknown scale and shift residing in per-frame prediction may cause the depth inconsistency.
