VSRD: Instance-Aware Volumetric Silhouette Rendering for Weakly Supervised 3D Object Detection

1 code implementation2 Apr 2024 Zihua Liu, Hiroki Sakuma and Masatoshi Okutomi

In the auto-labeling stage, we represent the surface of each instance as a signed distance field (SDF) and render its silhouette as an instance mask through our proposed instance-aware volumetric silhouette rendering.

CFDNet: A Generalizable Foggy Stereo Matching Network with Contrastive Feature Distillation

no code implementations28 Feb 2024 Zihua Liu, Yizhou Li, Masatoshi Okutomi

Stereo matching under foggy scenes remains a challenging task since the scattering effect degrades the visibility and results in less distinctive features for dense correspondence matching.

Digging Into Normal Incorporated Stereo Matching

1 code implementation ACM International Conference on Multimedia 2022 Zihua Liu, Songyan Zhang, Zhicheng Wang, Masatoshi Okutomi

To enhance geometric consistency, especially in low-texture regions, the estimated normal map is then leveraged to calculate a local affinity matrix, providing the residual learning with information about where the correction should refer and thus improving the residual learning efficiency.

Global Occlusion-Aware Transformer for Robust Stereo Matching

1 code implementation22 Dec 2023 Zihua Liu, Yizhou Li, Masatoshi Okutomi

Despite the remarkable progress facilitated by learning-based stereo-matching algorithms, the performance in the ill-conditioned regions, such as the occluded regions, remains a bottleneck.
