Learning Human Mesh Recovery in 3D Scenes

no code implementations CVPR 2023 Zehong Shen, Zhi Cen, Sida Peng, Qing Shuai, Hujun Bao, Xiaowei Zhou

We present a novel method for recovering the absolute pose and shape of a human in a pre-scanned scene given a single image.

Long-term Visual Localization with Mobile Sensors

no code implementations CVPR 2023 Shen Yan, Yu Liu, Long Wang, Zehong Shen, Zhen Peng, Haomin Liu, Maojun Zhang, Guofeng Zhang, Xiaowei Zhou

Despite the remarkable advances in image matching and pose estimation, image-based localization of a camera in a temporally-varying outdoor environment is still a challenging problem due to huge appearance disparity between query and reference images caused by illumination, seasonal and structural changes.

GIFT: Learning Transformation-Invariant Dense Visual Descriptors via Group CNNs

1 code implementation NeurIPS 2019 Yuan Liu, Zehong Shen, Zhixuan Lin, Sida Peng, Hujun Bao, Xiaowei Zhou

Instead of feature pooling, we use group convolutions to exploit underlying structures of the extracted features on the group, resulting in descriptors that are both discriminative and provably invariant to the group of transformations.
