Point Cloud Completion Guided by Prior Knowledge via Causal Inference

no code implementations28 May 2023 Songxue Gao, Chuanqi Jiao, Ruidong Chen, Weijie Wang, Weizhi Nie

In this paper, we propose a novel approach to point cloud completion task called Point-PC, which uses a memory network to retrieve shape priors and designs a causal inference model to filter missing shape information as supplemental geometric information to aid point cloud completion.

T2TD: Text-3D Generation Model based on Prior Knowledge Guidance

no code implementations25 May 2023 Weizhi Nie, Ruidong Chen, Weijie Wang, Bruno Lepri, Nicu Sebe

Meanwhile, to effectively integrate multi-modal prior knowledge into textual information, we adopt a novel multi-layer transformer structure to progressively fuse related shape and textual information, which can effectively compensate for the lack of structural information in the text and enhance the final performance of the 3D generation model.

Multigranular Visual-Semantic Embedding for Cloth-Changing Person Re-identification

no code implementations10 Aug 2021 Zan Gao, Hongwei Wei, Weili Guan, Weizhi Nie, Meng Liu, Meng Wang

To solve these issues, in this work, a novel multigranular visual-semantic embedding algorithm (MVSE) is proposed for cloth-changing person ReID, where visual semantic information and human attributes are embedded into the network, and the generalized features of human appearance can be well learned to effectively solve the problem of clothing changes.
