Intrusion Detection Framework for Invasive FPV Drones Using Video Streaming Characteristics

Cheap commercial off-the-shelf (COTS) First-Person View (FPV) drones have become widely available for consumers in recent years. Unfortunately, they also provide low-cost attack opportunities to malicious users. Thus, effective methods to detect the presence of unknown and non-cooperating drones within a restricted area are highly demanded....

EAVS: Edge-assisted Adaptive Video Streaming with Fine-grained Serverless Pipelines

Recent years have witnessed video streaming grad- ually evolve into one of the most popular Internet applications. With the rapidly growing personalized demand for real-time video streaming services, maximizing their Quality of Experience (QoE) is a long-standing challenge. The emergence of the server- less computing paradigm has potential to...

Improving the Computational Speed of a Tensor-Networked Kalman Filter for Streaming Video Completion

Streaming video completion is the practice that aims to fill in missing or corrupted pixels in a video stream by using past uncorrupted data. A method to tackle this problem is recently introduced called a Tensor Networked Kalman Filter (TNKF). It shows promising results in terms of performance compared to state-of-the-art methods for high...

Analysis of a streaming video feed of a pulverized coal injection system

Danieli Corus supplies tailor-made solutions for the global steel industry. Cameras are used in tuyeres of blast furnaces to detect physical aspects and irregularities. No operator could monitor those videos all day, which is why video analyses are needed. A program is written to analyse a test video and give information about the temperature,...

Improving the video streaming backend with on-the-fly format conversion and cloud storage

Online advanced media streaming services using HTTP adaptive stream-<br/>ing are increasingly popular. However in practice, the multi-protocol, multi-<br/>format nature of adaptive streaming creates a lot of engineering eort and<br/>costs for the operators, in the storage and preparation of the dierent<br/>formats. In this work, we acknowledge...

Improving mobile video quality through predictive channel quality based buffering

Frequent variations in throughput make mobile networks a challenging environment for video streaming. Current video players deal with those variations by matching video quality to network throughput. However, this adaptation strategy results in frequent changes of video resolution and bitrate, which negatively impacts the users' streaming...

Exposure Render Web Service

During the Bachelor End Project we have been tasked with developing a web portal for the Exposure Render. The Exposure Render is able to interactively visualize volumetric data to photo realistic images. This means that the web portal would allow users to view a visualization of their medical data.<br/>The requirements of the web portal have...

A model for evaluating sharing policies for network-assisted HTTP adaptive streaming

HTTP adaptive streaming (HAS) has become the dominant technology for streaming video over the Internet. It gained popularity because of its ability to adapt the video quality to the current network conditions and other appealing properties such as usage of off-the-shelf HTTP servers and easy firewall traversal. However, when multiple HAS...

Improving Peer-to-Peer Video Systems

Video Streaming is nowadays the Internet’s biggest source of consumer traffic. Traditional content providers rely on centralised client-server model for distributing their video streaming content. The current generation is moving from being passive viewers, or content consumers, to active content producers, and the traditional content...

Free-riding Resilient Video Streaming in Peer-to-Peer Networks

Performance Analysis of Chainsaw-based Live P2P Video Streaming

Due to the growing popularity of viewing media over the Internet, content servers are suffering from more and more stress every day. This problem is traditionally solved by enhancing the server infrastructure at the content provider, which is effective but also costly. A more cost effective solution would be to use P2P technology to distribute...

Give-to-Get: Free-riding-resilient Video-on-Demand in P2P Systems

Centralised solutions for Video-on-Demand (VoD) services, which stream pre-recorded video content to multiple clients who start watching at the moments of their own choosing, are not scalable because of the high bandwidth requirements of the central video servers. Peer-to-peer (P2P) techniques which let the clients distribute the video content...

Application-oriented link adaptation for IEEE 802.11

The thesis addresses the ever-persistent problem of quality guarantees in wireless data networks. The quality guarantees are especially important for real-time streaming applications. While in fixed links most of the quality issues could be, and are still resolved by over-provisioning, in the world of wireless communications things get...
