Fine-Granularity Transmission Distortion Modeling for Video Packet Scheduling Over Mesh Networks
Packet scheduling is a critical component in multi-session video streaming over mesh networks. Different video packets have different levels of contribution to the overall video presentation quality at the receiver side. In this work, we develop a fine-...
Cross-Media Alignment of Names and Faces
In this paper we report on our experiments on aligning names and faces as found in images and captions of online news Websites. Developing accurate technologies for linking names and faces is valuable when retrieving or mining information from ...
Camera Motion-Based Analysis of User Generated Video
In this paper we propose a system for the analysis of user generated video (UGV). UGV often has a rich camera motion structure that is generated at the time the video is recorded by the person taking the video, i.e., the ??camera person.?? We exploit ...
Representations of Keypoint-Based Semantic Concept Detection: A Comprehensive Study
Based on the local keypoints extracted as salient image patches, an image can be described as a ??bag-of-visual-words (BoW)?? and this representation has appeared promising for object and scene classification. The performance of BoW features in semantic ...
Network Awareness of P2P Live Streaming Applications: A Measurement Study
Early P2P-TV systems have already attracted millions of users, and many new commercial solutions are entering this market. Little information is however available about how these systems work, due to their closed and proprietary design. In this paper, ...
Impact of Network Dynamics on User's Video Quality: Analytical Framework and QoS Provision
We develop an analytical framework to investigate the impacts of network dynamics on the user perceived video quality. Our investigation stands from the end user's perspective by analyzing the receiver playout buffer. In specific, we model the playback ...
Synchronization of Multiple Camera Videos Using Audio-Visual Features
Digital video capturing is getting popular with the decreasing price of camcorders and the increasing availability of devices with embedded video cameras such as digital-still cameras, mobile phones and PDAs. While a raw home video is considered as ...
