As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

The phenomenology of Gaston Bachelard holds that readers, or viewers, relate to spatial imagery through the use of age-old archetypes. These archetypes form a collective image-memory that is employed when reading space. One such image is the house. The house for Bachelard is, however, never solely an image, but constitutes a familiar space that becomes inscribed in our bodies through the repeated physical contact with this domestic space. The house teaches us to interact with space, and comes to inform the way that human beings understand images of space.

The objective of this study was investigating social worker?s perspective of how alcohol consumption can affect, and what elements in the social environment that may be of significance for, alcohol consumption and development of identity. The questions at issue were: Do social workers experience any positive effects from alcohol consumption in 16-17 year-old girls with problematic alcohol consumption and what influence do the effects have on self esteem, self image and development of identity? What do social workers experience are the negative effects from alcohol consumption on self esteem, self image and development of identity? How important do social workers find the social environment and how do they believe the social environment affect the alcohol consumption and development of identity? This was investigated with a qualitative approach from a social worker?s perspective, hence social workers were interviewed. The study?s theoretical basis was Symbolic Interactionism and Erikson?s theory of Psychosocial Development.

With this essay I have tried to give an image of some Swedish teenagers opinions about Islam. I have also done research on how the Swedish school depicts Islam and how the media in Sweden and other western countries describe Islam and Muslims. I have come to the conclusion that the media do not give a positive image of Muslims and their religion. One the contrary, Muslims are talked about in relation to negative subjects. This is an image that seems to have influenced how young people in Sweden look at Muslims.I have handed out a questionnaire at schools in Kalmar and Jönköping, Sweden.

Syftet med denna uppsats är att analysera en enkät som Expansiva Växjö genomfört för att få en bild av Växjös image och undersöka hur nära denna ligger den önskade profilen. Därefter jämförs den strategi som valts för platsvarumärket Växjö med teorier om place branding och i vilken grad dessa tillämpas. Utifrån vår analys av Växjös image och strategi, samt med hjälp varumärkesteori, undersöks också om skapandet av varumärket har potential att bli framgångsrikt eller ej..

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.

AbstractTitle: The picture of the Swedish church - Young peoples image of the organization in comparison with the organizations profile (Bilden av Svenska kyrkan ? Unga människors image av organisationen i jämförelse med organisationens profil)Number of pages: 55 (57 including enclosures)Author: Ebba GöranzonTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the external communication of the Swedish Church, and how they want young people (16-18 years old) to perceive them. Further I would like to compare that information with how young people actually perceive the Swedish church. Do the both pictures agree?Method/Material: Together with literature studies, a qualitive method has been used and four focus group interviews with a total of 16 informants have been conducted.

North Korea has been on people?s minds lately. This essay is a study of what image Swedish press gave of North Korea starting in 1948 and ending in 2011. The study looks at two of the largest newspapers in Sweden, Aftonbladet and Dagens Nyheter.  During the 1950´s the image given was that North Korea was part of the communists, a puppet state of the Soviet Union.

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..

Syfte: Uppsatsens syfte är delvis att undersöka hur de valda aktörerna, det vill säga researrangörer och resetidningar, framställer en image av en destination. Delvis att beskriva och analysera marknadsföringen av exemplet Hong Kong som turistdestination i svenska resetidningar och hos svenska researrangörer samt undersöka svenskars uppfattade image av destinationen Hong Kong.Frågeställningar:Hur skapas en image av en destination?Vilken image av Hong Kong som destination förs fram i svenska resetidningar samt i researrangörers marknadsföring?Vilken uppfattad image har svenskar av destinationen Hong Kong?Metod: I uppsatsen används en kombination av kvalitativa och kvantitativa metoder. De tillvägagångssätt som används är kvalitativa intervjuer, analys av kvalitativ data samt en kvantitativ enkätundersökning.Teori: I den teoretiska referensramen diskuteras begrepp och fenomen som platser och destinationer, destinations- och platsmarknadsföring, imageskapande agenter och destinationsimage.Slutsats: I denna uppsats har två imageskapande aktörer studerats, och det har visats sig att processen för hur de skapar en destinations image ser olika ut, men den image som de presenterar överensstämmer till stor del. Hong Kong presenteras som en storstadsmetropol av både researrangörerna och resetidningarna.

The present work has been implemented as a literature study aimed to investigate the prevalence, possibly causes and consequences of an eating disorder. In today's modern society individuals are living with a constant reminder from the media about how a person should look and act to blend into the social norms and expectations of the modern society. This literature review has been analysed on the basis of concepts such as identity, gender identity and gender. In addition previous research has been analysed in terms of themes, history, possible causes/risk factors, media, body image and control, depression, shame and guilt as well as culture. The above themes were analysed on the basis of behaviouristic theory and role theory.
