Faithful learning with sure data for lung nodule diagnosis

no code implementations25 Feb 2022 Hanxiao Zhang, Liang Chen, Xiao Gu, Minghui Zhang, Yulei Qin, Feng Yao, Zhexin Wang, Yun Gu, Guang-Zhong Yang

In this study, we construct a sure dataset with pathologically-confirmed labels and propose a collaborative learning framework to facilitate sure nodule classification by integrating unsure data knowledge through nodule segmentation and malignancy score regression.

Egocentric Image Captioning for Privacy-Preserved Passive Dietary Intake Monitoring

no code implementations1 Jul 2021 Jianing Qiu, Frank P. -W. Lo, Xiao Gu, Modou L. Jobarteh, Wenyan Jia, Tom Baranowski, Matilda Steiner-Asiedu, Alex K. Anderson, Megan A McCrory, Edward Sazonov, Mingui Sun, Gary Frost, Benny Lo

In this paper, we propose a privacy-preserved secure solution (i. e., egocentric image captioning) for dietary assessment with passive monitoring, which unifies food recognition, volume estimation, and scene understanding.

Dual Attention Guided Gaze Target Detection in the Wild

1 code implementation CVPR 2021 Yi Fang, Jiapeng Tang, Wang Shen, Wei Shen, Xiao Gu, Li Song, Guangtao Zhai

In the third stage, we use the generated dual attention as guidance to perform two sub-tasks: (1) identifying whether the gaze target is inside or out of the image; (2) locating the target if inside.

Region-aware Adaptive Instance Normalization for Image Harmonization

1 code implementation CVPR 2021 Jun Ling, Han Xue, Li Song, Rong Xie, Xiao Gu

To ensure the visual style consistency between the foreground and the background, in this paper, we treat image harmonization as a style transfer problem.

Indoor Future Person Localization from an Egocentric Wearable Camera

no code implementations6 Mar 2021 Jianing Qiu, Frank P. -W. Lo, Xiao Gu, Yingnan Sun, Shuo Jiang, Benny Lo

Accurate prediction of future person location and movement trajectory from an egocentric wearable camera can benefit a wide range of applications, such as assisting visually impaired people in navigation, and the development of mobility assistance for people with disability.

Toward Fine-grained Facial Expression Manipulation

1 code implementation ECCV 2020 Jun Ling, Han Xue, Li Song, Shuhui Yang, Rong Xie, Xiao Gu

Previous methods edit an input image under the guidance of a discrete emotion label or absolute condition (e. g., facial action units) to possess the desired expression.

Query-free Clothing Retrieval via Implicit Relevance Feedback

no code implementations1 Nov 2017 Zhuoxiang Chen, Zhe Xu, Ya zhang, Xiao Gu

We model this problem as a new type of image retrieval task in which the target image resides only in the user's mind (called "mental image retrieval" hereafter).
