  1. 1. Local visual feature based localisation and mapping by mobile robots

    Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. LÄS MER

  3. 2. Low and Medium Level Vision Using Channel Representations

    Författare :Per-Erik Forssén; Gösta Granlund; Jim Little; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis introduces and explores a new type of representation for low and medium level vision operations called channel representation. The channel representation is a more general way to represent information than e.g. as numerical values, since it allows incorporation of uncertainty, and simultaneous representation of several hypotheses.

  4. 3. Semantic Mapping with Mobile Robots

    Författare :Andrzej Pronobis; Patric Jensfelt; Jim Little; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : After decades of unrealistic predictions and expectations, robots have finally escaped from industrial workplaces and made their way into our homes,offices, museums and other public spaces. These service robots are increasingly present in our environments and many believe that it is in the area ofservice and domestic robotics that we will see the largest growth within thenext few years.

  5. 4. An applied approach to numerically imprecise decision making

    Författare :Jim Idefeldt; Love Ekenberg; Mats Danielson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision tree; decision analysis; decision tool; imprecise reasoning; probability; Computer science; Datavetenskap;

    Sammanfattning : Despite the fact that unguided decision making might lead to inefficient and nonoptimal decisions, decisions made at organizational levels seldom utilise decisionanalytical tools. Several gaps between the decision-makers and the computer baseddecision tools exist, and a main problem in managerial decision-making involves the lack of information and precise objective data, i.

  7. 5. Bidding in Combinatorial Auctions

    Författare :Jim Wilenius; Arne Andersson; Peter Bro Miltersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; combinatorial auction; multiple-object; first-price; sealed-bid; game theory; multiple items; simultaneous auction; integer programming; equilibrium; strategy; reveue; Information technology; Informationsteknik; Datavetenskap; Computer Science;

    Sammanfattning : This thesis concerns the interdisciplinary field of combinatorial auctions, combining the fields of computer science, optimization and economics. A combinatorial auction is an auction where many items are sold simultaneously and where bidders may submit indivisible combinatorial bids on groups of items. LÄS MER
