Pedestrian detection for surveillance video, which is the basic of person re-identification, aims to capture the pedestrians in the monitors. However, the existing pedestrian detection algorithms still have two issues: (1) The recall and precision are not applicable for complicated scenes; (2) It is limited for processing the high-resolution video in real-time. Therefore, pedestrian detection algorithm...
In this paper, we focus on the quality of experience (QoE) optimization for dynamic adaptive streaming over HTTP (DASH) services. First, we propose a QoE evaluation model based on playback continuity, segment media quality and perceptual quality fluctuations caused by bitrate switching. Plenty of subjective mean-opinion-score (MOS) tests have shown a good correlation between this model and subjective...
With the development of Mobile and Wireless Network technology, Mobile learning (M-learning) becomes a focus after E-Learning. How can the farmers get requisite information of agricultural production by mobile phone? In order to solve this problem, the personalized mobile information system for the farmers has been designed and developed based on Ontology. It consists of four functional modules: information...
We will demonstrate a multi-user interaction system that uses Kinect and Wii Remote for manipulating windows in both desktop and wall-sized environment. This system combines the gesture information collected by Kinect and other sensor information such as acceleration from Wii Remote, therefore providing a more accurate control and a more nature experience for users.
Due to complexity, multiplicity and randomness of table tennis matches, it is necessary to develop some skill and tactic diagnostic models especially an efficient scoring model to get some skill and tactics data for table tennis matches. A scoring model is developed for table tennis matches based on video image processing technology. An input match video is used to analysis the skill and tactic of...
It is very important to analyze and synthesize sports video sequences efficiently for improving competition. Aiming at some limits existing in literature with complex computation and low efficiency in analysis sport video, a novel method has been developed to analyze and synthesize sport videos by intercepting pictures manually or automatically based on visual content. A group of continuous pictures...
As a new technology, network coding has very wide application in broadband wireless ad hoc networks and network coding theory has been applied in many fields such as P2P, application layer multicast, wireless Ad hoc networks, wireless sensor networks and wireless Mesh networks and so on. This paper presents a P2P streaming media transmission algorithm based on network coding technology which layers...
A novel image perceptual hashing method is proposed on the intermediate hashing stage. It first uses the iterative geometric techniques to get main geometric features. Then, by the observation that the distances of feature points are invariant in the polar coordinate under arbitrary rotation, a novel processing method is proposed to arrange the two-dimensional distribution to a one-dimensional feature...
We present an intelligent workload factoring service for enterprise customers to make the best use of public cloud services along with their privately-owned (legacy) data centers. It enables federation between on- and off-premise infrastructures for hosting Internet-based applications, and the intelligence lies in the explicit segregation of base workload and trespassing workload, the two naturally...
In this paper we measured and analyzed the workload on Yahoo! Video, the 2nd largest U.S. video sharing site, to understand its nature and the impact on online video data center design. We discovered interesting statistical properties on both static and temporal dimensions of the workload; they include file duration and popularity distributions, arrival rate dynamics and predictability, and workload...
An advanced sports video browsing and retrieval system based on multimodal analysis, SportsBR, is proposed in this work. Its main features include event-based sports video browsing and keyword-based sports video retrieval. The paper first defines the basic structure of our SportsBR system, and then introduces a novel approach that integrates multimodal analysis, such as visual streams analysis, speech...
