Adversarial Sparse-View CBCT Artifact Reduction
Haofu Liao, Zhimin Huo, William J. Sehnert +2
We present an effective post-processing method to reduce the artifacts from sparsely reconstructed cone-beam CT (CBCT) images. The proposed method is based on the state-of-the-art,…
Joint Vertebrae Identification and Localization in Spinal CT Images by Combining Short- and Long-Range Contextual Information
Haofu Liao, Addisu Mesfin, Jiebo Luo
Automatic vertebrae identification and localization from arbitrary CT images is challenging. Vertebrae usually share similar morphological appearance. Because of pathology and the…
Real-Time Referring Expression Comprehension by Single-Stage Grounding Network
Xinpeng Chen, Lin Ma, Jingyuan Chen +3
In this paper, we propose a novel end-to-end model, namely Single-Stage Grounding network (SSG), to localize the referent given a referring expression within an image. Different fr…
A Deep Multi-task Learning Approach to Skin Lesion Classification
Haofu Liao, Jiebo Luo
Skin lesion identification is a key step toward dermatological diagnosis. When describing a skin lesion, it is very important to note its body site distribution as many skin diseas…
Skin Disease Classification versus Skin Lesion Characterization: Achieving Robust Diagnosis using Multi-label Deep Neural Networks
Haofu Liao, Yuncheng Li, Jiebo Luo
In this study, we investigate what a practically useful approach is in order to achieve robust skin disease diagnosis. A direct approach is to target the ground truth diagnosis lab…
More Knowledge is Better: Cross-Modality Volume Completion and 3D+2D Segmentation for Intracardiac Echocardiography Contouring
Haofu Liao, Yucheng Tang, Gareth Funka-Lea +2
Using catheter ablation to treat atrial fibrillation increasingly relies on intracardiac echocardiography (ICE) for an anatomical delineation of the left atrium and the pulmonary v…
Face Completion with Semantic Knowledge and Collaborative Adversarial Learning
Haofu Liao, Gareth Funka-Lea, Yefeng Zheng +2
Unlike a conventional background inpainting approach that infers a missing area from image patches similar to the background, face completion requires semantic knowledge about the…
CariGAN: Caricature Generation through Weakly Paired Adversarial Learning
Wenbin Li, Wei Xiong, Haofu Liao +3
Caricature generation is an interesting yet challenging task. The primary goal is to generate plausible caricatures with reasonable exaggerations given face images. Conventional ca…
Unsupervised Image Captioning
Yang Feng, Lin Ma, Wei Liu +1
Deep neural networks have achieved great successes on the image captioning task. However, most of the existing models depend heavily on paired image-sentence datasets, which are ve…
Attentive Relational Networks for Mapping Images to Scene Graphs
Mengshi Qi, Weijian Li, Zhengyuan Yang +2
Scene graph generation refers to the task of automatically mapping an image into a semantic structural graph, which requires correctly labeling each extracted object and their inte…
How to Become Instagram Famous: Post Popularity Prediction with Dual-Attention
Zhongping Zhang, Tianlang Chen, Zheng Zhou +2
With a growing number of social apps, people have become increasingly willing to share their everyday photos and events on social media platforms, such as Facebook, Instagram, and…
Twitter Sentiment Analysis via Bi-sense Emoji Embedding and Attention-based LSTM
Yuxiao Chen, Jianbo Yuan, Quanzeng You +1
Sentiment analysis on large-scale social media data is important to bridge the gaps between social media contents and real world activities including political election prediction,…
Video Re-localization
Yang Feng, Lin Ma, Wei Liu +2
Many methods have been developed to help people find the video contents they want efficiently. However, there are still some unsolved problems in this area. For example, given a qu…
"Factual" or "Emotional": Stylized Image Captioning with Adaptive Learning and Attention
Tianlang Chen, Zhongping Zhang, Quanzeng You +4
Generating stylized captions for an image is an emerging topic in image captioning. Given an image as input, it requires the system to generate a caption that has a specific style…
A Multilayer Framework for Online Metric Learning
Wenbin Li, Yanfang Liu, Jing Huo +4
Online metric learning has been widely applied in classification and retrieval. It can automatically learn a suitable metric from data by restricting similar instances to be separa…
