Bagadus: An integrated real-time system for soccer analytics
Håkon Kvale Stensland,Vamsidhar Reddy Gaddam,Marius Tennøe,Espen Helgedagsrud,Mikkel Næss,Henrik Kjus Alstad,Asgeir Mortensen,Ragnar Langseth,Sigurd Ljødal,Østein Landsverk,Carsten Griwodz,Pål Halvorsen,Magnus Stenhaug,Dag Johansen +13 more
TL;DR: Bagadus is a real-time prototype of a sports analytics application using soccer as a case study, which integrates a sensor system, a soccer analytics annotations system, and a video processing system using a video camera array.
Journal ArticleDOI
Efficient disease detection in gastrointestinal videos --- global features versus neural networks
Konstantin Pogorelov,Michael Riegler,Sigrun Losada Eskeland,Thomas de Lange,Dag Johansen,Carsten Griwodz,Peter T. Schmidt,Pål Halvorsen +7 more
TL;DR: Initial experiments show that the complete end-to-end multimedia system presented has multi-class detection accuracy and polyp localization precision at least as good as state-of-the-art systems, and provides additional novelty in terms of real-time performance, low resource consumption and ability to extend with support for new classes of diseases.
Proceedings ArticleDOI
A network-layer proxy for bandwidth aggregation and reduction of IP packet reordering
Kristian Evensen,Dominik Kaspar,Paal E. Engelstad,Audun Fosselie Hansen,Carsten Griwodz,Pål Halvorsen +5 more
TL;DR: A multilink proxy able to transparently stripe traffic destined for multihomed clients is introduced that is able to fully aggregate the throughput of heterogeneous downlink streams, even if the path characteristics change over time.
Proceedings ArticleDOI
The fun of using TCP for an MMORPG
Carsten Griwodz,Pål Halvorsen +1 more
TL;DR: This work finds that Massive multi-player online games' kind of traffic has some interesting properties that inspire changes to protocol or architecture, and suggests a proxy architecture for multiplexing could save about 40% resources at the server, allow congestion control to work and also reduce the lag of the game.

Data segmentation, request and transfer method
Dominik Kaspar,Kristian Evensen,Paal E. Engelstad,Audun Fosselie Hansen,Carsten Griwodz,Pål Halvorsen +5 more
TL;DR: In this article, the authors describe a process for requesting information, the process including generating a plurality of range requests using a client having a plurality network interfaces, the range requests each corresponding to a data range of a data resource, transmitting, from the client having the plurality of network interfaces and receiving, at the client and from the server, a plurality-of-segments via the network interfaces such that each segment is received via a network interface which transmitted the corresponding range request, each segment including a portion of the data resource.
