Abnormal Event Detection and Location for Dense Crowds using Repulsive Forces and Sparse Reconstruction
Pei Lv, Shunhua Liu, Mingliang Xu +1
This paper proposes a method based on repulsive forces and sparse reconstruction for the detection and location of abnormal events in crowded scenes. In order to avoid the challeng…
USAR: an Interactive User-specific Aesthetic Ranking Framework for Images
Pei Lv, Meng Wang, Yongbo Xu +5
When assessing whether an image is of high or low quality, it is indispensable to take personal preference into account. Existing aesthetic models lay emphasis on hand-crafted feat…
Bi-directional Graph Structure Information Model for Multi-Person Pose Estimation
Jing Wang, Ze Peng, Pei Lv +3
In this paper, we propose a novel multi-stage network architecture with two branches in each stage to estimate multi-person poses in images. The first branch predicts the confidenc…
Depth Information Guided Crowd Counting for Complex Crowd Scenes
Mingliang Xu, Zhaoyang Ge, Xiaoheng Jiang +4
It is important to monitor and analyze crowd events for the sake of city safety. In an EDOF (extended depth of field) image with a crowded scene, the distribution of people is high…
Improving Aviation Safety using Synthetic Vision System integrated with Eye-tracking Devices
Mingliang Xu, Yibo Guo, Bailin Yang +4
By collecting the data of eyeball movement of pilots, it is possible to monitor pilot's operation in the future flight in order to detect potential accidents. In this paper, we des…
ART-UP: A Novel Method for Generating Scanning-robust Aesthetic QR codes
Mingliang Xu, Qingfeng Li, Jianwei Niu +4
QR codes are usually scanned in different environments, so they must be robust to variations in illumination, scale, coverage, and camera angles. Aesthetic QR codes improve the vis…
Stylize Aesthetic QR Code
Mingliang Xu, Hao Su, Yafei Li +5
With the continued proliferation of smart mobile devices, Quick Response (QR) code has become one of the most-used types of two-dimensional code in the world. Aiming at beautifying…
Efficiently Disassemble-and-Pack for Mechanism
Mingyuan Li, Xiaoheng Jiang, Ningbo Gu +4
In this paper, we present a disassemble-and-pack approach for a mechanism to seek a box which contains total mechanical parts with high space utilization. Its key feature is that m…
Crowd Behavior Simulation with Emotional Contagion in Unexpected Multi-hazard Situations
Mingliang Xu, Xiaozheng Xie, Pei Lv +6
In this paper we present a novel crowd simulation method by modeling the generation and contagion of panic emotion under multi-hazard circumstances. Specifically, we first classify…
Emotion-Based Crowd Simulation Model Based on Physical Strength Consumption for Emergency Scenarios
Mingliang Xu, Chaochao Li, Pei Lv +4
Increasing attention is being given to the modeling and simulation of traffic flow and crowd movement, two phenomena that both deal with interactions between pedestrians and cars i…
