Incorporating feature hierarchy and boosting to achieve more effective classifier training and concept-oriented video summarization and skimming
Hangzai Luo, Yuli Gao, Xiangyang Xue, Jinye Peng, Jianping Fan
Article No.: 1
For online medical education purposes, we have developed a novel scheme to incorporate the results of semantic video classification to select the most representative video shots for generating concept-oriented summarization and skimming of...
Rate-distortion optimized streaming of fine-grained scalable video sequences
Mohamed Hefeeda, Cheng-Hsin Hsu
Article No.: 2
We present optimal schemes for allocating bits of fine-grained scalable video sequences among multiple senders streaming to a single receiver. This allocation problem is critical in optimizing the perceived quality in peer-to-peer and distributed...
Video quality estimation in wireless IP networks: Algorithms and applications
Fulvio Babich, Marco D'orlando, Francesca Vatta
Article No.: 3
This article proposes three methods to estimate the distortion deriving from packet losses in wireless video communication. The proposed methods take into account the short-term properties of the encoded video sequences. A suitable set of...
Animations are a part of multimedia and techniques such as motion mapping and inverse kinematics aid in reusing models and motion sequences to create new animations. This reuse approach is facilitated by the use of content-based retrieval...
A revenue-rewarding scheme of providing incentive for cooperative proxy caching for media streaming systems
Alan T. S. Ip, John C. S. Lui, Jiangchuan Liu
Article No.: 5
Network entities cooperating together can improve system performance of media streaming. In this paper, we address the “incentive issue” of a cooperative proxy caching system and how to motivate each proxy to provide cache space...
An automated end-to-end lecture capture and broadcasting system
Cha Zhang, Yong Rui, Jim Crawford, Li-Wei He
Article No.: 6
Remote viewing of lectures presented to a live audience is becoming increasingly popular. At the same time, the lectures can be recorded for subsequent on-demand viewing over the Internet. Providing such services, however, is often prohibitive due...
Optimization of interactive visual-similarity-based search
Giang Phuong Nguyen, Marcel Worring
Article No.: 7
At one end of the spectrum, research in interactive content-based retrieval concentrates on machine learning methods for effective use of relevance feedback. On the other end, the information visualization community focuses on effective methods...
Hierarchical video patching with optimal server bandwidth
Helmut Hlavacs, Shelley Buchinger
Article No.: 8
Video patching is a way for transporting true video-on-demand, that is, instantaneous without any delay, from a video server to several clients. Instead of sending a unique stream to each newly arriving client, clients share as many multicast...
