TransPPG: Two-stream Transformer for Remote Heart Rate Estimate
Jiaqi Kang, Su Yang, Weishan Zhang
Non-contact facial video-based heart rate estimation using remote photoplethysmography (rPPG) has shown great potential in many applications (e.g., remote health care) and achieved…
Reinforcement Learning Based Sparse Black-box Adversarial Attack on Video Recognition Models
Zeyuan Wang, Chaofeng Sha, Su Yang
We explore the black-box adversarial attack on video recognition models. Attacks are only performed on selected key regions and key frames to reduce the high computation cost of se…
Video Anomaly Detection By The Duality Of Normality-Granted Optical Flow
Hongyong Wang, Xinjian Zhang, Su Yang +1
Video anomaly detection is a challenging task because of diverse abnormal events. To this task, methods based on reconstruction and prediction are wildly used in recent works, whic…
Risk Prediction on Traffic Accidents using a Compact Neural Model for Multimodal Information Fusion over Urban Big Data
Wenshan Wang, Su Yang, Weishan Zhang
Predicting risk map of traffic accidents is vital for accident prevention and early planning of emergency response. Here, the challenge lies in the multimodal nature of urban big d…
Anomaly Detection and Localization in Crowded Scenes by Motion-field Shape Description and Similarity-based Statistical Learning
Xinfeng Zhang, Su Yang, Xinjian Zhang +2
In crowded scenes, detection and localization of abnormal behaviors is challenging in that high-density people make object segmentation and tracking extremely difficult. We associa…
Neural Aesthetic Image Reviewer
Wenshan Wang, Su Yang, Weishan Zhang +1
Recently, there is a rising interest in perceiving image aesthetics. The existing works deal with image aesthetics as a classification or regression problem. To extend the cognitio…
