Analyzing interference between RGB-D cameras for human motion tracking

Multi-camera RGB-D systems are becoming popular as sensor setups in Computer Vision applications but they are prone to cause interference between them, compromising their accuracy. This paper extends previous works on the analysis of the noise introduced by interference with new and more realistic camera configurations and different brands of devices. As expected, the detected noise increases as distance and angle grows, becoming worse when interference is present. Finally, we evaluate the effectiveness of the proposed solutions of using DC vibration motors to mitigate them. The results of this study are being used to assess the effect of interference when applying these setups to human motion tracking.Universidad de Málaga.

Cyberbullying and traditional bullying in relation with adolescents’ perception of parenting

This study investigates the relation between parenting and involvement in cyberbullying. We predicted that cyberbullies and cyberbully-victims report less responsiveness and de manding reactions from their parents than victims and youthswho are not involved in cyberbullying. Furthermore, we predicted that youths with neglectful parents cyberbully the most often and youth with authoritative parents cyberbully the least. The same differences were predicted for traditional bullying. behavio and for youth involved in both forms of bullying behavior. Participants were made up to 1200 youths from 10-14 years old. They responded to a survey measuring cyberbullying and traditional bullying with questions based on the sub-scales from the Bully?Victim Questionnaire, and parenting with an adjusated version of the Parenting Style Questionnaire. Most results confirm out predictions. Results on authoritative, autoritarian, permissive and neglectful parenting styles suggest that for bullies, demanding actions are an important dimension of thier behavior and for victims, responsiveness is an important dimension of their behavior
