Human perception of haptic-to-video and haptic-to-audio skew in multimedia applications
Juan M. Silva, Mauricio Orozco, Jongeun Cha, Abdulmotaleb El Saddik, Emil M. Petriu
Article No.: 9
DOI: 10.1145/2457450.2457451

The purpose of this research is to assess the sensitivity of humans to perceive asynchrony among media signals coming from a computer application. Particularly we examine haptic-to-video and haptic-to-audio skew. For this purpose we have designed...

A reward-and-punishment-based approach for concept detection using adaptive ontology rules
Chidansh A. Bhatt, Pradeep K. Atrey, Mohan S. Kankanhalli
Article No.: 10
DOI: 10.1145/2457450.2457452

Despite the fact that performance improvements have been reported in the last years, semantic concept detection in video remains a challenging problem. Existing concept detection techniques, with ontology rules, exploit the static correlations...

Identity verification based on handwritten signatures with haptic information using genetic programming
Fawaz A. Alsulaiman, Nizar Sakr, Julio J. Valdés, Abdulmotaleb El Saddik
Article No.: 11
DOI: 10.1145/2457450.2457453

In this article, haptic-based handwritten signature verification using Genetic Programming (GP) classification is presented. A comparison of GP-based classification with classical classifiers including support vector machine, k-nearest...

Multifeature analysis and semantic context learning for image classification
Qianni Zhang, Ebroul Izquierdo
Article No.: 12
DOI: 10.1145/2457450.2457454

This article introduces an image classification approach in which the semantic context of images and multiple low-level visual features are jointly exploited. The context consists of a set of semantic terms defining the classes to be associated to...

Modeling the effect of user interactions on mesh-based P2P VoD streaming systems
Zhen Wei Zhao, Sameer Samarth, Wei Tsang Ooi
Article No.: 13
DOI: 10.1145/2457450.2457455

User interactions such as seeks and pauses are widely supported by existing Peer-to-Peer Video-on-Demand (P2P VoD) streaming systems. Their effect on the streaming system, however, has not been well studied. Seeks cause peers to skip part of the...

Effective transfer tagging from image to video
Yang Yang, Yi Yang, Heng Tao Shen
Article No.: 14
DOI: 10.1145/2457450.2457456

Recent years have witnessed a great explosion of user-generated videos on the Web. In order to achieve an effective and efficient video search, it is critical for modern video search engines to associate videos with semantic keywords...

APRICOD: An access-pattern-driven distributed caching middleware for fast content discovery of noncontinuous media access
Zhen Wei Zhao, Wei Tsang Ooi
Article No.: 15
DOI: 10.1145/2457450.2457457

Content discovery is a major source of latency in peer-to-peer (P2P) media streaming systems, especially in the presence of noncontinuous user access, such as random seek in Video-on-Demand (VoD) streaming and teleportation in a Networked Virtual...
