Computational Spectral Imaging with Unified Encoding Model: A Comparative Study and Beyond

no code implementations20 Dec 2023 Xinyuan Liu, Lizhi Wang, Lingen Li, Chang Chen, Xue Hu, Fenglong Song, Youliang Yan

Computational spectral imaging is drawing increasing attention owing to the snapshot advantage, and amplitude, phase, and wavelength encoding systems are three types of representative implementations.

Rethinking Boundary Discontinuity Problem for Oriented Object Detection

1 code implementation17 May 2023 Hang Xu, Xinyuan Liu, Haonan Xu, Yike Ma, Zunjie Zhu, Chenggang Yan, Feng Dai

We decouple reversibility and joint-optim from single smoothing function into two distinct entities, which for the first time achieves the objectives of both correcting angular boundary and blending angle with other parameters. Extensive experiments on multiple datasets show that boundary discontinuity problem is well-addressed.

Gaussian Label Distribution Learning for Spherical Image Object Detection

no code implementations CVPR 2023 Hang Xu, Xinyuan Liu, Qiang Zhao, Yike Ma, Chenggang Yan, Feng Dai

Therefore, we propose GLDL-ATSS as a better training sample selection strategy for objects of the spherical image, which can alleviate the drawback of IoU threshold-based strategy of scale-sample imbalance.

Bidirectional Loss Function for Label Enhancement and Distribution Learning

no code implementations7 Jul 2020 Xinyuan Liu, Jihua Zhu, Qinghai Zheng, Zhongyu Li, Ruixin Liu, Jun Wang

More specifically, this novel loss function not only considers the mapping errors generated from the projection of the input space into the output one but also accounts for the reconstruction errors generated from the projection of the output space back to the input one.

Generalized Label Enhancement with Sample Correlations

no code implementations7 Apr 2020 Qinghai Zheng, Jihua Zhu, Haoyu Tang, Xinyuan Liu, Zhongyu Li, Huimin Lu

Recently, label distribution learning (LDL) has drawn much attention in machine learning, where LDL model is learned from labelel instances.
