A Sketch-Based Approach for Interactive Organization of Video Clips
Yong-Jin Liu, Cui-Xia Ma, Qiufang Fu, Xiaolan Fu, Sheng-Feng Qin, Lexing Xie
Article No.: 2
DOI: 10.1145/2645643

With the rapid growth of video resources, techniques for efficient organization of video clips are becoming appealing in the multimedia domain. In this article, a sketch-based approach is proposed to intuitively organize video clips by: (1)...

Circle & Search: Attribute-Aware Shoe Retrieval
Junshi Huang, Si Liu, Junliang Xing, Tao Mei, Shuicheng Yan
Article No.: 3
DOI: 10.1145/2632165

Taking the shoe as a concrete example, we present an innovative product retrieval system that leverages object detection and retrieval techniques to support a brand-new online shopping experience in this article. The system, called Circle &...

A Top-Down Approach for Video Summarization
Genliang Guan, Zhiyong Wang, Shaohui Mei, Max Ott, Mingyi He, David Dagan Feng
Article No.: 4
DOI: 10.1145/2632267

While most existing video summarization approaches aim to identify important frames of a video from either a global or local perspective, we propose a top-down approach consisting of scene identification and scene summarization. For scene...

PROPANE: A Progressive Panorama Streaming Protocol to Support Interactive 3D Virtual Environment Exploration on Graphics-Constrained Devices
Richard W. Pazzi, Azzedine Boukerche
Article No.: 5
DOI: 10.1145/2602222

Image-Based Rendering (IBR) has become widely known by its relatively low requirements for generating new scenes based on a sequence of reference images. This characteristic of IBR shows a remarkable potential impact in rendering complex 3D...

Up-Fusion: An Evolving Multimedia Fusion Method
Xiangyu Wang, Yong Rui, Mohan Kankanhalli
Article No.: 6
DOI: 10.1145/2611777

The amount of multimedia data on the Internet has increased exponentially in the past few decades and this trend is likely to continue. Multimedia content inherently has multiple information sources, therefore effective fusion methods are critical...

Exploration in Interactive Personalized Music Recommendation: A Reinforcement Learning Approach
Xinxi Wang, Yi Wang, David Hsu, Ye Wang
Article No.: 7
DOI: 10.1145/2623372

Current music recommender systems typically act in a greedy manner by recommending songs with the highest user ratings. Greedy recommendation, however, is suboptimal over the long term: it does not actively gather information on user preferences...

Online Estimation of Evolving Human Visual Interest
Harish Katti, Anoop Kolar Rajagopal, Mohan Kankanhalli, Ramakrishnan Kalpathi
Article No.: 8
DOI: 10.1145/2632284

Regions in video streams attracting human interest contribute significantly to human understanding of the video. Being able to predict salient and informative Regions of Interest (ROIs) through a sequence of eye movements is a challenging...
