Weakly Supervised Detection of Baby Cry
Weijun Tan, Qi Yao, Jingfeng Liu
Detection of baby cries is an important part of baby monitoring and health care. Almost all existing methods use supervised SVM, CNN, or their varieties. In this work, we propose t…
Overlooked Video Classification in Weakly Supervised Video Anomaly Detection
Weijun Tan, Qi Yao, Jingfeng Liu
Current weakly supervised video anomaly detection algorithms mostly use multiple instance learning (MIL) or their varieties. Almost all recent approaches focus on how to select the…
Two-Stage COVID19 Classification Using BERT Features
Weijun Tan, Qi Yao, Jingfeng Liu
We propose an automatic COVID1-19 diagnosis framework from lung CT-scan slice images using double BERT feature extraction. In the first BERT feature extraction, A 3D-CNN is first u…
Detection of Fights in Videos: A Comparison Study of Anomaly Detection and Action Recognition
Weijun Tan, Jingfeng Liu
Detection of fights is an important surveillance application in videos. Most existing methods use supervised binary action recognition. Since frame-level annotations are very hard…
Balanced Masked and Standard Face Recognition
Delong Qi, Kangli Hu, Weijun Tan +2
We present the improved network architecture, data augmentation, and training strategies for the Webface track and Insightface/Glint360K track of the masked face recognition challe…
A 3D CNN Network with BERT For Automatic COVID-19 Diagnosis From CT-Scan Images
Weijun Tan, Jingfeng Liu
We present an automatic COVID1-19 diagnosis framework from lung CT-scan slice images. In this framework, the slice images of a CT-scan volume are first proprocessed using segmentat…
YOLO5Face: Why Reinventing a Face Detector
Delong Qi, Weijun Tan, Qi Yao +1
Tremendous progress has been made on face detection in recent years using convolutional neural networks. While many face detectors use designs designated for detecting faces, we tr…
A Dataset and System for Real-Time Gun Detection in Surveillance Video Using Deep Learning
Delong Qi, Weijun Tan, Zhifu Liu +2
Gun violence is a severe problem in the world, particularly in the United States. Deep learning methods have been studied to detect guns in surveillance video cameras or smart IP c…
