Alexandros Stergiou and I have compiled a comprehensive overview of literature on computer vision-based approaches to detect human-human interactions in videos, with a focus on recent CNN-based work. Under review, but already available on Arxiv!
In a user study into online insurance fraud, we found that people are more dishonest when they are rejected. It appears that the negative feeling ellicited by rejection, rather than a loss in monetary reward, drives this process. The research paper appears in Frontiers in Psychology, and already appears in the list of most downloaded papers.
On April 21, Alejandro Moreno successfully defended his PhD thesis “From Traditional to Interactive Playspaces: Automatic Analysis of Player Behavior in the Interactive Tag Playground”. Congratulations!
He will now continue this exciting work as a postdoctoral researcher at the University of Twente. In the mean time, check out the accepted Entertainment Computing paper on subjective and objective evaluation of technology-enhanced playgrounds.
An open-access paper by Alejandro Moreno and me is published at the Journal on Multimodal User Interfaces (JMUI). Download it here. We discuss how to automate the analysis of behavior of playing children. We compare traditional tag with an interactive version played in our Interactive Playground. We also introduce two algorithms for the detection of tagger and runner roles by looking at interactions between children.
Zhigang Tu‘s paper “Weighted Local Intensity Fusion Method for Variational Optical Flow Estimation” has been accepted for the Pattern Recognition journal, and can be found online already. Congratulations! The paper presents several advances in the estimation of movement from video. Zhigang will defend his PhD thesis on November 16.
