Adaptive media playout for low-delay video streaming over error-prone channels
This paper shows how adaptive media playout (AMP), the variation of the playout speed of media frames depending on channel conditions, allows the client to buffer less data, thus introducing less delay, for a given buffer underflow probability. Expand
Real-time compression of point cloud streams
This work presents a novel lossy compression approach for point cloud streams which exploits spatial and temporal redundancy within the point data and presents a technique for comparing the octree data structures of consecutive point clouds. Expand
Perception-Based Data Reduction and Transmission of Haptic Data in Telepresence and Teleaction Systems
The experimental results show that the presented approach is able to reduce the packet rate between an operator and a teleoperator by up to 90% of the original rate without affecting the performance of the system. Expand
Application-driven cross-layer optimization for video streaming over wireless networks
This article proposes a cross-layer optimization strategy that jointly optimizes the application layer, data link layer, and physical layer of the protocol stack using an application-oriented objective function in order to maximize user satisfaction. Expand
Graph-based data fusion of pedometer and WiFi measurements for mobile indoor positioning
This work proposes a graph-based, low-complexity sensor fusion approach for ubiquitous pedestrian indoor positioning using mobile devices to combine relative motion information based on step detection with WiFi signal strength measurements based on the well-known particle filter methodology. Expand
Multimodal Feature-Based Surface Material Classification
The proposed subset of six features, selected from the described sound, image, friction force, and acceleration features, leads to a classification accuracy of 74 percent in the authors' experiments when combined with a Naive Bayes classifier. Expand
IEEE Transactions on Circuits and Systems for Video Technology
Event analysis in videos is a critical task in many applications. Activity recognition that aims to recognize actions from video and in particular abnormal event recognition in surveillance video hasExpand
Haptic Communications
Haptic communications is stressed the fact that it is not meant as a replacement of traditional audiovisual communications but rather as an additional dimension for telepresence that will allow us to advance in the authors' quest for truly immersive communication. Expand
MOS-Based Multiuser Multiapplication Cross-Layer Optimization for Mobile Multimedia Communication
A novel optimization scheme based on the mean opinion score (MOS) as the unifying metric over different application classes is defined, and it is confirmed that MOS-based optimization leads to significant improvement in terms of user perceived quality when compared to conventional throughput- based optimization.

QoE-Based Traffic and Resource Management for Adaptive HTTP Video Delivery in LTE
This paper presents proactive and reactive QoE optimization approaches for adapting the adaptive HTTP video delivery in an long-term evolution network and shows that by jointly solving for the streaming and transmission rates, the wireless network resources are more efficiently allocated among the users and substantial gains in the user perceived video quality can be achieved.
