From 3D Sensing to Printing: A Survey
Longyu Zhang, Haiwei Dong, Abdulmotaleb El Saddik
Article No.: 27
DOI: 10.1145/2818710

Three-dimensional (3D) sensing and printing technologies have reshaped our world in recent years. In this article, a comprehensive overview of techniques related to the pipeline from 3D sensing to printing is provided. We compare the latest 3D...

QoE-Driven Rate Adaptation Heuristic for Fair Adaptive Video Streaming
Stefano Petrangeli, Jeroen Famaey, Maxim Claeys, Steven Latré, Filip De Turck
Article No.: 28
DOI: 10.1145/2818361

HTTP Adaptive Streaming (HAS) is quickly becoming the de facto standard for video streaming services. In HAS, each video is temporally segmented and stored in different quality levels. Rate adaptation heuristics, deployed at the video player,...

Scalable Object Retrieval with Compact Image Representation from Generic Object Regions
Shaoyan Sun, Wengang Zhou, Qi Tian, Houqiang Li
Article No.: 29
DOI: 10.1145/2818708

In content-based visual object retrieval, image representation is one of the fundamental issues in improving retrieval performance. Existing works adopt either local SIFT-like features or holistic features, and may suffer sensitivity to noise or...

Multiview Image Block Compressive Sensing with Joint Multiphase Decoding for Visual Sensor Network
Mansoor Ebrahim, Wai Chong Chia
Article No.: 30
DOI: 10.1145/2818712

In this article, a multiview image compression framework, which involves the use of Block-based Compressive Sensing (BCS) and Joint Multiphase Decoding (JMD), is proposed for a Visual Sensor Network (VSN). In the proposed framework, one of the...

Opinion Question Answering by Sentiment Clip Localization
Lei Pang, Chong-Wah Ngo
Article No.: 31
DOI: 10.1145/2818711

This article considers multimedia question answering beyond factoid and how-to questions. We are interested in searching videos for answering opinion-oriented questions that are controversial and hotly debated. Examples of questions include...

Improving Concept-Based Image Retrieval with Training Weights Computed from Tags
Vasileios Papapanagiotou, Christos Diou, Anastasios Delopoulos
Article No.: 32
DOI: 10.1145/2790230

This article presents a novel approach to training classifiers for concept detection using tags and a variant of Support Vector Machine that enables the usage of training weights per sample. Combined with an appropriate tag weighting mechanism,...

Automatic Generation of Visual-Textual Presentation Layout
Xuyong Yang, Tao Mei, Ying-Qing Xu, Yong Rui, Shipeng Li
Article No.: 33
DOI: 10.1145/2818709

Visual-textual presentation layout (e.g., digital magazine cover, poster, Power Point slides, and any other rich media), which combines beautiful image and overlaid readable texts, can result in an eye candy touch to attract users’...

Measuring Collectiveness via Refined Topological Similarity
Xuelong Li, Mulin Chen, Qi Wang
Article No.: 34
DOI: 10.1145/2854000

Crowd system has motivated a surge of interests in many areas of multimedia, as it contains plenty of information about crowd scenes. In crowd systems, individuals tend to exhibit collective behaviors, and the motion of all those individuals is...

Measurements and Analysis of a Major Adult Video Portal
Gareth Tyson, Yehia Elkhatib, Nishanth Sastry, Steve Uhlig
Article No.: 35
DOI: 10.1145/2854003

Today, the Internet is a large multimedia delivery infrastructure, with websites such as YouTube appearing at the top of most measurement studies. However, most traffic studies have ignored an important domain: adult multimedia distribution....

Finding Social Points of Interest from Georeferenced and Oriented Online Photographs
Bart Thomee, Ioannis Arapakis, David A. Shamma
Article No.: 36
DOI: 10.1145/2854004

Points of interest are an important requirement for location-based services, yet they are editorially curated and maintained, either professionally or through community. Beyond the laborious manual annotation task, further complications arise as...
