Low-light Stereo Image Enhancement and De-noising in the Low-frequency Information Enhanced Image Space

1 code implementation15 Jan 2024 Minghua Zhao, Xiangdong Qin, Shuangli Du, Xuefei Bai, Jiahao Lyu, Yiguang Liu

First, to reduce unwanted noise interference, a low-frequency information enhanced module (IEM) is proposed to suppress noise and produce a new image space.

PHI-MVS: Plane Hypothesis Inference Multi-view Stereo for Large-Scale Scene Reconstruction

no code implementations13 Apr 2021 Shang Sun, Yunan Zheng, Xuelei Shi, Zhenyu Xu, Yiguang Liu

Besides, a new acceleration scheme similar to dilated convolution can speed up the depth map estimating process with only a slight influence on the reconstruction.

Learning Structral coherence Via Generative Adversarial Network for Single Image Super-Resolution

1 code implementation25 Jan 2021 Yuanzhuo Li, Yunan Zheng, Jie Chen, Zhenyu Xu, Yiguang Liu

Among the major remaining challenges for single image super resolution (SISR) is the capacity to recover coherent images with global shapes and local details conforming to human vision system.

Disentanglement Then Reconstruction: Learning Compact Features for Unsupervised Domain Adaptation

no code implementations28 May 2020 Lihua Zhou, Mao Ye, Xinpeng Li, Ce Zhu, Yiguang Liu, Xue Li

By this reconstructor, we can construct prototypes for the original features using class prototypes and domain prototypes correspondingly.

A random algorithm for low-rank decomposition of large-scale matrices with missing entries

no code implementations4 Nov 2014 Yiguang Liu

The vectors are the null vectors of the corresponding submatrix in the ground truth of the given large-scale matrix.

A Probabilistic Framework for Multitarget Tracking with Mutual Occlusions

no code implementations CVPR 2014 Menglong Yang, Yiguang Liu, Longyin Wen, Zhisheng You, Stan Z. Li

Mutual occlusions among targets can cause track loss or target position deviation, because the observation likelihood of an occluded target may vanish even when we have the estimated location of the target.
