Learning Semantic Abstraction of Shape via 3D Region of Interest

no code implementations13 Jan 2022 Haiyue Fang, Xiaogang Wang, Zheyuan Cai, Yahao Shi, Xun Sun, Shilin Wu, Bin Zhou

This is in contrast to current methods, which focus solely on either 3D shape abstraction or semantic analysis.

Learning Fine-Grained Segmentation of 3D Shapes without Part Labels

no code implementations CVPR 2021 Xiaogang Wang, Xun Sun, Xinyu Cao, Kai Xu, Bin Zhou

Learning-based 3D shape segmentation is usually formulated as a semantic labeling problem, assuming that all parts of training shapes are annotated with a given set of tags.

A Dataset for Benchmarking Image-Based Localization

no code implementations CVPR 2017 Xun Sun, Yuanfan Xie, Pei Luo, Liang Wang

One of the evident limitations of existing datasets is that precise ground truth camera poses of query images are not available in a meaningful 3D metric system.

Segment-Tree Based Cost Aggregation for Stereo Matching

no code implementations CVPR 2013 Xing Mei, Xun Sun, Wei-Ming Dong, Haitao Wang, Xiaopeng Zhang

Instead of employing the minimum spanning tree (MST) and its variants, a new tree structure, "Segment-Tree", is proposed for non-local matching cost aggregation.
