CCAE: A Corpus of Chinese-based Asian Englishes

no code implementations9 Oct 2023 Yang Liu, Melissa Xiaohui Qin, Long Wang, Chao Huang

The ontology of data would make the corpus a helpful resource with enormous research potential for Asian Englishes (especially for Chinese Englishes for which there has not been a publicly accessible corpus yet so far) and an ideal source for variety-specific language modeling and downstream tasks, thus setting the stage for NLP-based World Englishes studies.

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.

Exponential Consensus of Multiple Agents over Dynamic Network Topology: Controllability, Connectivity, and Compactness

no code implementations1 Mar 2023 Qichao Ma, Jiahu Qin, Brian D. O. Anderson, Long Wang

Based on this notion, it is shown that by designing a proper feedback matrix and under the precompactness assumption, exponential consensus can be reached globally and uniformly if the joint $(\delta, T)$-connectivity and controllability conditions are satisfied, and the synchronization index is not less than one.

Deep Active Contours for Real-time 6-DoF Object Tracking

no code implementations ICCV 2023 Long Wang, Shen Yan, Jianan Zhen, Yu Liu, Maojun Zhang, Guofeng Zhang, Xiaowei Zhou

Specifically, given an initial pose, we project the object model to the image plane to obtain the initial contour and use a lightweight network to predict how the contour should move to match the true object boundary, which provides the gradients to optimize the object pose.
