Using Paired Distances of Signal Peaks in Stereo Channels as Fingerprints for Copy Identification
Shingchern D. You, Yi-Han Pu
Article No.: 1
DOI: 10.1145/2742059

This article proposes to use the relative distances between adjacent envelope peaks detected in stereo audio as fingerprints for copy identification. The matching algorithm used is the rough longest common subsequence (RLCS) algorithm. The...

QoE-Based Cross-Layer Optimization for Uplink Video Transmission
Ali El Essaili, Zibin Wang, Eckehard Steinbach, Liang Zhou
Article No.: 2
DOI: 10.1145/2801124

We study the problem of resource-efficient uplink distribution of user-generated video content over fourth-generation mobile networks. This is challenged by (1) the capacity-limited and time-variant uplink channel, (2) the resource-hungry...

CelebrityNet: A Social Network Constructed from Large-Scale Online Celebrity Images
Li-Jia Li, David A. Shamma, Xiangnan Kong, Sina Jafarpour, Roelof Van Zwol, Xuanhui Wang
Article No.: 3
DOI: 10.1145/2801125

Photos are an important information carrier for implicit relationships. In this article, we introduce an image based social network, called CelebrityNet, built from implicit relationships encoded in a collection of celebrity images. We...

Segmentation of Discriminative Patches in Human Activity Video
Bo Zhang, Nicola Conci, Francesco G.B. De Natale
Article No.: 4
DOI: 10.1145/2750780

In this article, we present a novel approach to segment discriminative patches in human activity videos. First, we adopt the spatio-temporal interest points (STIPs) to represent significant motion patterns in the video sequence. Then, nonnegative...

Wireless Multicast for Zoomable Video Streaming
Hui Wang, Mun Choon Chan, Wei Tsang Ooi
Article No.: 5
DOI: 10.1145/2801123

Zoomable video streaming refers to a new class of interactive video applications, where users can zoom into a video stream to view a selected region of interest in higher resolutions and pan around to move the region of interest. The zoom and pan...

User Preferences Modeling and Learning for Pleasing Photo Collage Generation
Simone Bianco, Gianluigi Ciocca
Article No.: 6
DOI: 10.1145/2801126

In this article, we consider how to automatically create pleasing photo collages created by placing a set of images on a limited canvas area. The task is formulated as an optimization problem. Differently from existing state-of-the-art approaches,...

QoE-Based SVC Layer Dropping in LTE Networks Using Content-Aware Layer Priorities
Bo Fu, Dirk Staehle, Gerald Kunzmann, Eckehard Steinbach, Wolfgang Kellerer
Article No.: 7
DOI: 10.1145/2754167

The increasing popularity of mobile video streaming applications has led to a high volume of video traffic in mobile networks. As the base station, for instance, the eNB in LTE networks, has limited physical resources, it can be overloaded by this...

Area of Simulation: Mechanism and Architecture for Multi-Avatar Virtual Environments
Siqi Shen, Shun-Yun Hu, Alexandru Iosup, Dick Epema
Article No.: 8
DOI: 10.1145/2764463

Although Multi-Avatar Distributed Virtual Environments (MAVEs) such as Real-Time Strategy (RTS) games entertain daily hundreds of millions of online players, their current designs do not scale. For example, even popular RTS games such as the...

Link-Aware Reconfigurable Point-to-Point Video Streaming for Mobile Devices
Suk Kyu Lee, Seungho Yoo, Jongtack Jung, Hwangnam Kim, Jihoon Ryoo
Article No.: 9
DOI: 10.1145/2771438

Even though people of all social standings use current mobile devices in the wide spectrum of purpose from entertainment tools to communication means, some issues with real-time video streaming in hostile wireless environment still exist. In this...

Combining Acoustic and Multilevel Visual Features for Music Genre Classification
Ming-Ju Wu, Jyh-Shing R. Jang
Article No.: 10
DOI: 10.1145/2801127

Most music genre classification approaches extract acoustic features from frames to capture timbre information, leading to the common framework of bag-of-frames analysis. However, time-frequency analysis is also vital for modeling music genres....
