MonoDiffusion: Self-Supervised Monocular Depth Estimation Using Diffusion Model

1 code implementation13 Nov 2023 Shuwei Shao, Zhongcai Pei, Weihai Chen, Dingchi Sun, Peter C. Y. Chen, Zhengguo Li

Because the depth ground-truth is unavailable in the training phase, we develop a pseudo ground-truth diffusion process to assist the diffusion in MonoDiffusion.

Constrained Exploration in Reinforcement Learning with Optimality Preservation

no code implementations5 Apr 2023 Peter C. Y. Chen

We then extend this structure by adding a supervisor to ensure that the behavior of the agent meets the specification, and establish (for a class of reinforcement-learning problems with a known deterministic environment) a necessary and sufficient condition under which optimality is preserved.

ALIKE: Accurate and Lightweight Keypoint Detection and Descriptor Extraction

2 code implementations6 Dec 2021 Xiaoming Zhao, Xingming Wu, Jinyu Miao, Weihai Chen, Peter C. Y. Chen, Zhengguo Li

The reprojection loss is then proposed to directly optimize these sub-pixel keypoints, and the dispersity peak loss is presented for accurate keypoints regularization.
