Popular Abstract in Swedish I takt med att vi översvämmas av kameror och bilder blir också tillämpningarna för automatiserad bildanalys allt större. Det kan handla om avancerade industrirobotar eller mobiltelefoner och syftet är allt från att rädda liv till att få en bra bild på barnbarnen. Den här avhandlingen fokuserar på två centrala problem inom fältet datorseende och bildanalys. Den första dThis thesis focuses on two problems in the field of computer vision and image analysis. The first part of the thesis deals with image localization. The goal is simply to answer the question: Where was this picture taken? To answer this two things are needed: A model of the world, or at least the relevant parts of the world, and a method for relating a new image to the model. The thesis presents ne

Skogsvårdslagen är en författning som gäller parallellt med miljöbalken. Lagen är uppbyggd kring att produktions- och miljömål ska vara likvärdiga. I praktiken ser det annorlunda ut då produktionsintresset ofta överordnas miljöintresset, vilket resulterar i att den biologiska mångfalden i skogslandskapet blir lidande. SVL ställer få krav på skogsägarna. Myndigheternas strategi är att med rådgivnin

PM in diesel exhaust has been given much attention due to its adverse effect on both climate and health. As the PM emission levels are tightened, the portion of particles originating from the lubrication oil is likely to increase. In this study, exhausts from a biodiesel-fueled Euro 5 engine were examined to determine how much of the carbonaceous particles that originated from the fuel and the lub

Some extraordinary people have dedicated their lives to making art pieces out of long dead organisms. One of them is Esben Horn, founder of model shop 10 Tons Studios on the outskirts of Copenhagen, Denmark. A bona fide 'master of puppets', he makes jaw-dropping replicas for museums around the world, with the utmost respect for science and organismal anatomy. Recently, our joint efforts resulted i

A set of pre- and post-storm beach profile data was assembled and the profiles classified into seven different cross-shore morphology change types resulting from overwash. These were crest accumulation, dune/berm translation, dune lowering, dune destruction, barrier accretion, short-term barrier rollover, and barrier destruction. Pre- and post-storm barrier profile sets from recent laboratory expe

This study is motivated by two research questions: (1) How is an organizational control system established and maintained in product and process innovation? (2) How are innovation processes facilitated or hindered as a result of the interplay between forms of control and autonomy? The thesis investigates these questions by means of an in-depth longitudinal case study involving 15 innovation projec

Sustainable lifestyles and consumption refer to multiple spheres of human activities such as mobility, housing, food and leisure. Increasingly consumers are called upon to assume greater responsibility for changing their lifestyles, primarily through making environmentally sound purchasing choices and changing behavior. To motivate consumers, governments have often focused on improving the provisi

OBJECTIVES: Breast Imaging-Reporting and Data System (BI-RADS) mammographic density categories are associated with considerable interobserver variability. Automated methods of measuring volumetric breast density may reduce variability and be valuable in risk and mammographic screening stratification. Our objective was to assess agreement of mammographic density by a volumetric method with the radi

Andersson M., Klaesson J. and Larsson J. P. How local are spatial density externalities? Neighbourhood effects in agglomeration economies, Regional Studies. The geographic scale at which density externalities operate is analysed in this paper. Using geocoded high-resolution data, the analysis is focused on exogenously determined within-city squares (‘neighbourhoods’) of 1 km2. The analysis confirm
