Modeling video viewing behaviors for viewer state estimation

Ryo Yonetani
2012 Proceedings of the 20th ACM international conference on Multimedia - MM '12  
Our goal is to establish a method to estimate the viewer states from his/her eye movements toward general videos, such as TV news and commercials.  ...  This model realizes statistical learning of gaze information while considering dynamic characteristics of video scenes to achieve viewer-state estimation.  ...  Viewer states are here assumed to be represented by one of several discrete states, such as "focusing on a certain object in a video", "paying attention to a video", and further, "favoring a video".  ...

Applied Cliplets-based half-dynamic videos as intervention learning materials to attract the attention of adolescents with autism spectrum disorder to improve their perceptions and judgments of the facial expressions and emotions of others

I-Jui Lee, Chien-Hsu Chen, Ling-Yi Lin
2016 SpringerPlus  
Objective: In this study, we used software technology to create half-static and dynamic video materials to teach adolescents with ASD how to become aware of six basic facial expressions observed in real  ...  Autism spectrum disorders (ASD) are characterized by a reduced ability to understand the emotional expressions on other people's faces.  ...  I would also like to thank the individuals who participated in this research and the autism associations in Taiwan.  ...

Understanding embodied visual attention in child-parent interaction

Sven Bambach, David J. Crandall, Chen Yu
2013 2013 IEEE Third Joint International Conference on Development and Learning and Epigenetic Robotics (ICDL)  
A key component of the human visual system is our attentional control -the selection of which visual stimuli to pay attention to at any moment in time.  ...  We data-mine this data to study the distributions of gaze patterns within the first-person visual frame for both children and adults.  ...  This is likely caused by parents paying attention to both objects in their own hands as well as monitoring the objects in a child's hands.  ...

Interpretable Self-Attention Temporal Reasoning for Driving Behavior Understanding

Yi-Chieh Liu, Yung-An Hsieh, Min-Hung Chen, C.-H. Huck Yang, J. Tegner, Y.-C. James Tsai
2020 ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
By examining the video attention saliency, we found that existing models could not precisely capture the causes (e.g., traffic light) of the specific action (e.g., stopping).  ...  The attention saliency also demonstrated that TRB helped models focus on the causes more precisely.  ...  The visual explanation aims at understanding where the models are paying attention to. In other words, it generates the attention saliency of the input data.  ...

2016 2016 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)  
Such objects of joint attention are expected to act as an important cue for understanding social interactions in everyday scenes.  ...  The goal of this work is to discover objects of joint attention, i.e., objects being viewed by multiple people using head-mounted cameras and eye trackers.  ...  Such objects of joint attention reflect what people attend to from moment to moment and can be used as a cue to understand group activities [8, 28] .  ...

A Novel Perceptual Image Encryption Scheme Using Geometric Objects Based Kernel

Prabhudev Jagadeesh, P. Nagabhushan, R. Pradeep Kumar
2013 International Journal of Computer Science & Information Technology (IJCSIT)  
The wide use of digital images and videos in various applications warrant serious attention to the security and privacy issues today.  ...  In many applications, such as pay-per-view videos, pay-TV and video on demand, one of the required features is that the quality of the video data be degraded only partially by some encryption technique  ...  Subjective measurements can be used to corroborate the usefulness of objective measurements. Therefore objective methods have engrossed more attentions in recent years [12] .  ...

Humans but Not Chimpanzees Vary Face-Scanning Patterns Depending on Contexts during Action Observation

Masako Myowa-Yamakoshi, Chisato Yoshida, Satoshi Hirata, Rachel L Kendal
2015 PLoS ONE  
These results suggest that in humans, but not chimpanzees, attention to actor's faces conveying referential information toward the target object indicates the process of observers making inferences about  ...  However, little is known about how this information is integrated with action understanding.  ...  When and why do human adults pay more attention to an actor's face, especially when a possible goal is not achieved?  ...
