Video chat apps enable users to stay in touch with their family, friends and colleagues. However, they consume a lot of bandwidth and hence can quickly use up a monthly data plan quota, which is a high-cost resource on smartphones. In this paper, we ...

To compose high-quality movies directors need life-long learning and talent. User-generated video defines a new era of video production in which non-professionals record videos and share them on platforms such as YouTube. As hiring professional ...

Recently, researchers have proposed solutions to build on-device mobile visual search (ODMVS) systems. Different from traditional client-server mobile visual search systems, an ODMVS supports image searching directly within a mobile device. An ODMVS ...

The current approach to transcoding in adaptive bit rate streaming is to transcode all videos in all possible bit rates which wastes transcoding resources and storage space, since a large fraction of the transcoded video segments are never watched by ...

More and more users are watching online videos produced by non-professional sources (e.g., gamers, teachers of online courses, witnesses of public events) by using an increasingly diverse set of devices to access the videos (e.g., smartphones, tablets, ...

In recent years, adaptive HTTP streaming protocols have become the de-facto standard in the industry for the distribution of live and video-on-demand content over the Internet. This paper presents SmoothCache 2.0, a distributed cache platform for ...

In this paper, we present a novel application for elucidating all kind of videos that require expert knowledge, e.g., sport videos, medical videos etc., focusing on endoscopic surgery and video capsule endoscopy. In the medical domain, the knowledge of ...

Social networks have become ubiquitous and with these new possible ways for social communication and experiencing multimedia together the traditional TV scenario drifts more and more towards a distributed social experience. Asynchronism in the ...

Energy consumption is an important concern for mobile devices, where the evolution in battery storage capacity has not followed the power usage requirements of modern hardware. However, innovative and flexible hardware platforms give developers better ...

Mobile network operators are expected to face significant traffic increase in the upcoming years. One alternative method is to intelligently move transmissions to times of network underutilization, either on 3G/4G or by offloading to WiFi. Video content,...

All computer games present some delay between human input and results being displayed on the screen, even when no networking is involved. A well-balanced discussion of delay-tolerance levels in computer games requires an understanding of how much delay ...

By processing video footage from a camera array, one can easily make wide-field-of-view panorama videos. From the single panorama video, one can further generate multiple virtual cameras supporting personalized views to a large number of users based on ...

Motivated by our systematic study on the diverse aspects of migrating gaming services to a virtualized cloud environment, we designed and implemented a fully virtualized cloud gaming platform, Rhizome, utilizing the latest hardware support for both ...

In this demonstration, we present an open, flexible and realistic benchmarking platform named Video BenchLab to measure the performance of streaming media workloads. While Video BenchLab can be used with any existing media server, we provide a set of ...

Although AR has a long history in the area of maintenance and service-support in industry, there still is a lack of lightweight, yet practical solutions for handheld AR systems in everyday workflows. Attempts to support complex maintenance tasks with AR ...

Augmented Reality (AR) and Augmented Virtuality (AV) systems have been used in various fields such as entertainment, broadcasting, gaming [1], etc. Collaborative AR or AV (CAR/CAV) systems are a special kind of such system in which the interaction ...

We present a study of depth-disparity calibration for augmented reality applications using binocular optical see-through displays. Two techniques were proposed and compared. The "paired-eyes" technique leverages the Panum's fusional area to help viewer ...

In wireless networks such as those based on IEEE 802.11, packet losses due to fading and interference are often misinterpreted as indications of congestion, causing unnecessary decrease in the data sending rate due to congestion control at higher layer ...

We present an integrated prefetching and caching proxy, termed iPac, for HTTP-based adaptive video streaming services like Netflix and YouTube. The challenge we address is maximizing the byte-hit ratio for proxies through prefetching in the context of ...

Although the capacity of cellular networks has increased with recent generations, the growth in demand of wireless bandwidth has outpaced this increase in capacity. Not only more users are relying on wireless networks, but also the demand from each user ...

In this paper, we present an open, flexible and realistic benchmarking platform named Video BenchLab to measure the performance of streaming media workloads. While Video BenchLab can be used with any existing media server, we provide a set of tools for ...

Dynamic and adaptive binding between computing devices and displays is increasingly more popular, and screencast technologies enable such binding over wireless networks. In this paper, we design and conduct the first detailed measurement study on the ...

Video-on-Demand (VoD) and video sharing services account for a large percentage of the total downstream Internet traffic. In order to provide a better understanding of the load on these services, we analyze and model a workload trace from a VoD service ...

We present a novel dataset for multi-view video and spatial audio. An ensemble of ten musicians from the BBC Philharmonic Orchestra performed in the orchestra's rehearsal studio in Salford, UK, on 25th March 2014. This presented a controlled environment ...

In this paper we introduce a new dataset and its evaluation tools, Div150Cred, that was designed to support shared evaluation of diversification techniques in different areas of social media photo retrieval and related areas. The dataset comes with ...

With video streaming becoming more and more popular, the number of devices that are capable of streaming videos over the Internet is growing. This leads to a heterogeneous device landscape with varying demands. Dynamic Adaptive Streaming over HTTP (DASH)...

Digital forensics is a relatively new research area which aims at authenticating digital media by detecting possible digital forgeries. Indeed, the ever increasing availability of multimedia data on the web, coupled with the great advances reached by ...

User-Generated live video streaming systems are services that allow anybody to broadcast a video stream over the Internet. These Over-The-Top services have recently gained popularity, in particular with e-sport, and can now be seen as competitors of the ...
