Handling of IP-Addresses in the Context of Remote Access
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad For various reasons (e.g., security, lack of IPv4-addresses) the services in the home smart space only use private IP addresses. This is unfortunate in the remote service access since these addresses frequently appear in responses sent from a service in the remote smart space (e.g., your home) to the visited smart space (e.g., your friend’s home).The Internet Engineering Task Force (IETF) provides some solutions and workarounds for the problem caused by NAT. In this project, the challenge to me is to summarize the available options, rank the options according to which one is preferred for the RA-…
Wavelet-based video compression: A glimpse of the future?
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad Even though wavelet-based video compression has been an area of research for more than a decade, motion estimation and compensation has been considered complex and inefficient until recently. We have carried out a thorough investigation of existing research work in this field, and found that fundamental problem with wavelet-based temporal removal while obtaining highly scalability (the wavelet-properties of multiresolution structure in combination with embedded coding), has been solved by performing motion compensated temporal filtering within the wavelet domain of a overcomplete three-dimensional li…
Analysis of binarization techniques and Tsetlin machine architectures targeting image classification
2020
Master's thesis in Information- and communication technology (IKT590) The Tsetlin Machine is a constantly evolving and developing machine learning technique with ever-increasing success. However, for every success, the Tsetlin Machine achieves, a new set of challenges are put ahead. To sufficiently bring the Tsetlin Machine to a broadly used standard, these challenges must be completed. This thesis focuses on the challenge of doing color image classification and will provide an introductory description of how this is possible through the usage of an older technique, namely binarization. A comparison with the various Tsetlin Machine adaptations made public in recent times is also present aft…
An improved image processing chain for mobile terminals
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad Based on the proposal in the report by Tryggve Mikkelsen [Mikkelsen, 2001] this thesis investigates and discusses the implementation of a simplified image processing chain for modern mobile terminals. Previous work on image processing in this field of application has shown that the demosaicing operation, color space conversion and downsampling are resource demanding pre-processing operations. The simplification potential of the signal chain lies within the pictured scenario of using Bayer RGB from the image sensor directly as input to the compression scheme. By omitting these pre-processing operation…
Deep Convolutional Neural Networks for Semantic Segmentation of Multi-Band Satellite Images
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 Semantic segmentation of images is of increasing interest in the eld of computer vision and machine learning. Accurate and e cient segmentation methods is required for many of todays modern applications. This the- sis provides a review of deep learning methods for semantic segmentation of satellite images. Firstly, we compare di erent state-of-the-art methods. Next, we explore the bene ts of using multiple spectral bands of data as compared to the traditional RGB bands. Finally, a look at future possibil- ities with segmentation using capsule networks.
Combining Deep Privacy with an Attribute-driven Generative Adversarial Network to Preserve Gender and Age in De-identified CCTV Footage
2021
Master's thesis in Information- and communication technology (IKT590) A surveillance camera is an efficient solution to prohibit crimes for both small and big businesses, and is broadly utilized in big cities. Today, the police force can only access the camera footage for further investigation after an act of crime. In order to observe, find patterns, and react appropriately to an event, the Oslo Police wants to use its own CCTV cameras and analyze such footage in real-time. To investigate real-time CCTV footage and share such footage with a third-party for analyzing, the people in the footage need to be de-identified. In this thesis, we focus on de-identification of CCTV footage, preservin…
Hand Gestures Recognition using Thermal Images
2021
Master's thesis in Information- and communication technology (IKT590) Hand gesture recognition is important in a variety of applications, including medical systems and assistive technologies, human-computer interaction, human-robot interaction, industrial automation, virtual environment control, sign language translation, crisis and disaster management, en-tertainment and computer games, and robotics. RGB cameras are usually used for most of these applications. However, their performance is limited especially in low-light conditions. It is challenging to accurately classify the hand gestures in dark conditions. In this thesis, we propose the robust hand gestures recognition based on high re…
Research on the impact of using interactive game based learning to teach mathematics
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad The number of students who study scientific subjects has continued to drop over a long period of time. Compared to 2004, there is a 12% decrease in High School students who study mathematics and a 5% decrease in applicants for technology studies at College and University level in 2005 [1]. These numbers concern employees of the technology sector as they have predicted a large need for mathematicians in the future [19]. The educational system is under constant change to take advantage of new educational methods that modern technology allows for. The Heriot Watt University in Scotland showed that the i…
Interconnected learning automata playing Iterated Prisoner's Dilemma
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad There exist several examples of situations where interaction between entities is essential in order to reach a common goal, for instance negotiations. Problems arise when the parties of a case are in disagreement with each other and they all want the best for themselves. Our thesis focuses around one such case. Analyzing the results of its own actions, an entity can learn what kind of adversaries it faces. For instance they may be cooperative, hostile, ignorant or irrational. The situation becomes even more complex when the opposing parties change its behaviour while trying to reach a goal. In this c…
Data management and concurrency control in broadcast based asymmetric environments
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Tens of millions of users have personal handheld devices with several network interfaces built-in, and the number of users and of network interfaces included are only increasing. This growth suggests a need for new methods to disseminate data to multiple clients, and cyclic broadcast is one approach. We do a survey on the various data management protocols that describe how to broadcast the data, and the concurrency control protocols that make sure all access to the database is consistent. The various data management and concurrency control techniques deals with the restrictions in asymmetric broadcas…
